ui: Ensure value is always passed to CONSUL_SSO_ENABLED (#7913)
ACLsEnabled is always set to either true or false. .SSOEnabled is only set if you are running enterprise (the same as .NamespacesEnabled). Therefore .SSOEnabled and .NamespacesEnabled require conditionals to check their existence.

In order to avoid future confusion we moved all go-template variables to use the conditional form, and added a comment to that effect.

Tests have been added to reflect this, but they only test that the template outputs what we expect, true e2e testing here would be advantageous.

John Cowen 412eec7f5d UI: Improved Login/Logout flow inc SSO support (#7790)
* 6 new components for new login/logout flow, plus SSO support

UI Components:

1. AuthDialog: Wraps/orchestrates AuthForm and AuthProfile
2. AuthForm: Authorization form shown when logged out.
3. AuthProfile: Simple presentational component to show the users
'Profile'
4. OidcSelect: A 'select' component for selecting an OIDC provider,
dynamically uses either a single select menu or multiple buttons
depending on the amount of providers

Data Components:

1. JwtSource: Given an OIDC provider URL this component will request a
token from the provider and fire an donchange event when it has been
retrieved. Used by TokenSource.
2. TokenSource: Given a oidc provider name or a Consul SecretID,
TokenSource will use whichever method/API requests required to retrieve
Consul ACL Token, which is emitted to the onchange event handler.

Very basic README documentation included here, which is likely to be
refined somewhat.

* CSS required for new auth/SSO UI components

* Remaining app code required to tie the new auth/SSO work together

* CSS code required to help tie the auth/SSO work together

* Test code in order to get current tests passing with new auth/SSO flow

..plus extremely basics/skipped rendering tests for the new components

* Treat the secret received from the server as the truth

Previously we've always treated what the user typed as the truth, this
breaks down when using SSO as the user doesn't type anything to retrieve
a token. Therefore we change this so that we use the secret in the API
response as the truth.

* Make sure removing an dom tree from a buffer only removes its own tree

ui: Acceptance test improvements to prepare for more NS tests (#6980)
* ui: Acceptance test improvements to prepare for more NS tests

* ui: Namespace acceptance testing (#7005)

* Update api-double and consul-api-double for http.body

* Adds places where we missed passing the nspace through

* Hardcode nspace CRUD to use the default nspace for policies and roles

* Alter test helpers to allow us to control nspaces from the outside

* Amends to allow tests to account for namespace, move ns from queryParam

1. We decided to move how we pass the namespace value through to the
backend when performing write actions (create, update). Previoulsy we
were using the queryParam although using the post body is the preferred
method to send the Namespace details through to the backend.
2. Other various amends to take into account testing across multiple
namespaced scenarios

* Enable nspace testing by default

* Remove last few occurances of old style http assertions

We had informally 'deprecated' our old style of http assertions that
relied on the order of http calls (even though that order was not
important for the assertion). Following on from our namespace work we
removed the majority of the old occrances of these old style assertions.

This commit removes the remaining few, and also then cleans up the
assertions/http.js file to only include the ones we are using.

This reduces our available step count further and prevents any confusion
over the usage of the old types and the new types.

* ui: Namespace CRUD acceptance tests (#7016)

* Upgrade consul-api-double

* Add all the things required for testing:

1. edit and index page objects
2. enable CONSUL_NSPACE_COUNT cookie setting
3. enable mutating HTTP response bodies based on URL

* Add acceptance test for nspace edit/delete/list and searching

ui: UI Release Merge (ui-staging merge) (#6527)
## HTTPAdapter (#5637)

## Ember upgrade 2.18 > 3.12 (#6448)

### Proxies can no longer get away with not calling _super

This means that we can't use create anymore to define dynamic methods.
Therefore we dynamically make 2 extended Proxies on demand, and then
create from those. Therefore we can call _super in the init method of
the extended Proxies.

### We aren't allowed to reset a service anymore

We never actually need to now anyway, this is a remnant of the refactor
from browser based confirmations. We fix it as simply as possible here
but will revisit and remove the old browser confirm functionality at a
later date

### Revert classes to use ES5 style to workaround babel transp. probs

Using a mixture of ES6 classes (and hence super) and arrow functions
means that when babel transpiles the arrow functions down to ES5, a
reference to this is moved before the call to super, hence causing a js
error.

Furthermore, we the testing environment no longer lets use use
apply/call on the constructor.

These errors only manifests during testing (only in the testing
environment), the application itself runs fine with no problems without
this change.

Using ES5 style class definitions give us freedom to do all of the above
without causing any errors, so we reverted these classes back to ES5
class definitions

### Skip test that seems to have changed due to a change in RSVP timing

This test tests a usecase/area of the API that will probably never ever
be used, it was more testing out the API. We've skipped the test for now
as this doesn't affect the application itself, but left a note to come
back here later to investigate further

### Remove enumerableContentDidChange

Initial testing looks like we don't need to call this function anymore,
the function no longer exists

### Rework Changeset.isSaving to take into account new ember APIs

Setting/hanging a computedProperty of an instantiated object no longer
works. Move to setting it on the prototype/class definition instead

### Change how we detect whether something requires listening

New ember API's have changed how you can detect whether something is a
computedProperty or not. It's not immediately clear if its even possible
now. Therefore we change how we detect whether something should be
listened to or not by just looking for presence of `addEventListener`

### Potentially temporary change of ci test scripts to ensure deps exist

All our tooling scripts run through a Makefile (for people familiar with
only using those), which then call yarn scripts which can be called
independently (for people familar with only using yarn).

The Makefile targets always check to make sure all the dependencies are
installed before running anything that requires them (building, testing
etc).

The CI scripts/targets didn't follow this same route and called the yarn
scripts directly (usually CI builds a cache of the dependencies first).

For some reason this cache isn't doing what it usually does, and it
looks as though, in CI, ember isn't installed.

This commit makes the CI scripts consistently use the same method as all
of the other tooling scripts (Makefile target > Install Deps if
required > call yarn script). This should install the dependencies if
for some reason the CI cache building doesn't complete/isn't successful.

Potentially this commit may be reverted if, the root of the problem is
elsewhere, although consistency is always good, so it might be a good
idea to leave this commit as is even if we need to debug and fix things
elsewhere.

### Make test-parallel consistent with the rest of the tooling scripts

As we are here making changes for CI purposes (making test-ci
consistent), we spotted that test-parallel is also inconsistent and also
the README manual instructions won't work without `ember` installed
globally.

This commit makes everything consistent and changes the manual
instructions to use the local ember instance that gets installed via
yarn

### Re-wrangle catchable to fit with new ember 3.12 APIs

In the upgrade from ember 3.8 > 3.12 the public interfaces for
ComputedProperties have changed slightly. `meta` is no longer a public
property of ComputedProperty but of a ComputedDecoratorImpl mixin
instead.

7e4ba1096e/packages/%40ember/-internals/metal/lib/computed.ts (L725)

There seems to be no way, by just using publically available
methods, to replicate this behaviour so that we can create our own
'ComputedProperty` factory via injecting the ComputedProperty class as
we did previously.

3f333bada1/ui-v2/app/utils/computed/factory.js (L1-L18)

Instead we dynamically hang our `Catchable` `catch` method off the
instantiated ComputedProperty. In doing it like this `ComputedProperty`
has already has its `meta` method mixed in so we don't have to manually
mix it in ourselves (which doesn't seem possible)

This functionality is only used during our work in trying to ensure
our EventSource/BlockingQuery work was as 'ember-like' as possible (i.e.
using the traditional Route.model hooks and ember-like Controller
properties). Our ongoing/upcoming work on a componentized approach to
data a.k.a `<DataSource />` means we will be able to remove the majority
of the code involved here now that it seems to be under an amount of
flux in ember.

John Cowen 834479d56f ui: Upgrade ember-cli-api-double. Adds new staging env (#6136)
ember-cli-api-double has been upgraded for 3 things:

1. Use the correct configuration flags
2. Automatically include the necessary files to enable the api doubles
without requiring a server. This can be disabled to provide custom
functionality (so we can stitch our BDD style testing in with this)
3. When used statically, read the cookies from the users browser to
enable basic ad-hoc double editing (e.g. CONSUL_SERVICE_COUNT=100000)

Once upgraded we've now moved the config to the correct place, added a
new environment (staging) to use the static-style of doubles
The test environment continues to use custom cookie setting and url
checking so we disable this 'auto importing' by setting 'auto-import' to
false for the configuration for the addon.

We also added a couple of new package script targets to explicitly serve
or build the UI with the entirely static UI.

John Cowen 466c3c6899 ui: Allow text selection of clickable elements and their contents (#5770)
* ui: Allow text selection of clickable elements and their contents

This commit disables a click on mousedown be removing the `href`
attribute and moving it to a `data-href` attribute. On mouseup it will
only move it back if there is no selection. This means that an anchor
will only be followed on click _if_ there is no selection.

This fixes the fact that whenever you select some copy within a
clickable element it immediately throws you into the linked page when
you release your mouse.

Further notes:

We use the `isCollapsed` property here which 'seems' to be classed as
'experimental' in one place where I researched it:

https://developer.mozilla.org/en-US/docs/Web/API/Selection/isCollapsed

Although in others it makes no mention of this 'experimental' e.g:

- https://webplatform.github.io/docs/dom/Selection/isCollapsed/
- https://w3c.github.io/selection-api/#dom-selection-iscollapsed

I may have gone a little overboard in feature detection for this, but I
conscious of that fact that if `isCollapsed` doesn't exist at some point
in the future (something that seems unlikely). The code here will have
no effect on the UI. But I'd specifically like a second pair of eyes on
that.

* ui: Don't break right click, detects a secondary click on mousedown

* ui: Put anchor selection capability behind an ENV var

John Cowen 1625a09372 ui: Adds blocking query support to the service detail page (#5479)
This commit includes several pieces of functionality to enable services
to be removed and the page to present information that this has happened
but also keep the deleted information on the page. Along with the more
usual blocking query based listing.

To enable this:

1. Implements `meta` on the model (only available on collections in
ember)
2. Adds new `catchable` ComputedProperty alongside a `listen` helper for
working with specific errors that can be thrown from EventSources in an
ember-like way. Briefly, normal computed properties update when a
property changes, EventSources can additionally throw errors so we can
catch them and show different visuals based on that.

John Cowen 04308c8e8d Move testing doubles to use data embedded in the HTML vs HTTP/fetch
Previously `api-double` usage in ember would require a bunch of `fetch`
requests to pull in the 'api double', this had a number of disadvantages.

1. The doubles needed to be available via HTTP, which meant a short term
solution of rsyncing the double files over to `public` in order to be served
over HTTP. An alternative to that would have been figuring out how to serve
something straight from `node_modules`, which would have been preferable.

2. ember/testem would not serve dot files (so anything starting with a
., like `.config`. To solve this via ember/testem would have involved
digging in to understand how to enable the serving of dot files.

3. ember/testem automatically rewrote urls for non-existant files to
folders, i.e. adding a slash for you, so `/v1/connect/intentions` would
be rewritten to `/v1/connect/intentions/`. This is undesirable, and
solving this via ember/testem would have involved digging deep to
disable that.

Serving the files via HTTP has now changed. The double files are now
embedded into the HTML has 'embedded templates' that can be found by
using the url of the file and a simple `querySelector`. This of course
only happens during testing and means I can fully control the 'serving'
of the doubles now, so I can say goodbye to the need to move files
around, worry about the need to serve dotfiles and the undesirable
trailing slashes rewriting. Winner!

Find the files and embedding them is done using a straightforward
recursive-readdir-sync (the `content-for` functionality is a synchronous
api) as oppose to getting stuck into `broccoli`.
