ui: Reduce discovery-chain log errors (#8065)
* ui: Reduce discovery-chain log spam

Currently the only way that the UI can know whether connect is enabled
or not is whether we get 500 errors from certain endpoints.

One of these endpoints we already use, so aswell as recovering from a
500 error, we also remember that connect is disabled for the rest of the
page 'session' (so until the page is refreshed), and make no further
http requests to the endpoint for that specific datacenter.

This means that log spam is reduced to only 1 log per page refresh/dc
instead of 1 log per service navigation.

Longer term we'll need some way to dynamically discover whether connect
is enabled per datacenter without relying on something that will add
error logs to consul.

This commit deletes CSS that we no longer use and we definitely will not

We also dedup all of our imports here as it turns out SASS doesn't
dedupe imports. Strangely this increases out CSS weight by ~1kb instead
of reducing but we'd rather keep things deduped as that was the
intention

* Refactor FeedbackDialog and CopyButton

* Change this.element to use `{{ref }}` now we don't have an element

We changed this to a tagless component with an eye to moving this to a
glimmer component, without spotting that this would also remove the
`this.element` property.

This adds an equivalent using the ref modifier.

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

* Create PopoverSelect component and styling

* Create CatalogToolbar component and Styling

* ui: Adds `selectable-key-values` helper (#7472)

Preferably we want all copy/text to live in the template. Whilst you can
achieve what we've done here with a combination of different helpers, as
we will be using this approach in various places it's probably best to
make a helper.

We also hit an ember bug related to using the `let` helper and trying to
access `thingThatWasLet.firstObject` (which can also be worked around
using `object-at`).

Moving everything to a helper 'sorted' everything.

Probably worthwhile noting that if the sort option themselves become
dynamic, I'm not sure if the helper here would actually react as you
would expect (I'm aware that ember helpers on react on the root
arguments, not necesarily sub properties of those arguments). If we get
to that point this helper could take the same approach as what I believe
ember-composable-helpers does to get around this, or move them to the
view controller. If we do ever moved this to the view controller, we
can still use the exported function from the new helper here to keep
using the same functionality and tests we have here.

* Create tests for sorting services with CatalogToolbar

* Add rule to print 'ember/no-global-jquery' as a warning

John Cowen e34c16a90c ui: Logout button (#7604)
* ui: Logout button

This commit adds an easier way to logout of the UI using a logout button

Notes:

- Added a Logout button to the main navigation when you are logged in,
meaning you have easy access to a way to log out of the UI.
- Changed all wording to use 'Log in/out' vocabulary instad of 'stop
using'.
- The logout button opens a panel to show you your current ACL
token and a logout button in order to logout.
- When using legacy ACLs we don't show the current ACL token as legacy
ACLs tokens only have secret values, whereas the new ACLs use a
non-secret ID plus a secret ID (that we don't show).
- We also added a new `<EmptyState />` component to use for all our
empty states. We currently only use this for the ACLs disabled screen to
provide more outgoing links to more readind material/documentation to
help you to understand and enable ACLs.
- The `<DataSink />` component is the sibling to our `<DataSource />`
component and whilst is much simpler (as it doesn't require polling
support), its tries to use the same code patterns for consistencies
sake.
- We had a fun problem with ember-data's `store.unloadAll` here, and in
the end went with `store.init` to empty the ember-data store instead due
to timing issues.
- We've tried to use already existing patterns in the Consul UI here
such as our preexisting `feedback` service, although these are likely to
change in the future. The thinking here is to add this feature with as
little change as possible.

Overall this is a precursor to a much larger piece of work centered on
auth in the UI. We figured this was a feature complete piece of work as
it is and thought it was worthwhile to PR as a feature on its own, which
also means the larger piece of work will be a smaller scoped PR also.

John Cowen 17f10ffd0d ui: Add tab navigation to the browser history/URLs (#7592)
* ui: Add tab navigation to the browser history/URLs

This commit changes all our tabbed UI interfaces in the catalog to use
actual URL changes rather than only updating the content in the page
using CSS.

Originally we had decided not to add tab clicks into the browser
history for a variety of reasons. As the UI has progressed these tabs
are a fairly common pattern we are using and as the UI grows and
stabilizes around certain UX patterns we've decided to make these tabs
'URL changing'.

Pros:

- Deeplinking
- Potentially smaller Route files with a more concentrated scope of the
contents of a tab rather than the entire page.
- Tab clicks now go into your history meaning backwards and forwards
buttons take you through the tabs not just the pages.
- The majority of our partials are now fully fledged templates (Octane
🎉)

Cons:

- Tab clicks now go into your history meaning backwards and forwards
buttons take you through the tabs not just the pages. (Could be good and
bad from a UX perspective)
- Many more Route and Controller files (yet as mentioned above each of these
have a more reduced scope)
- Moving around the contents of these tabs, or changing the visual names
of them means updates to the URL structure, which then should
potentially entail redirects, therefore what things that seem like
straightforwards design reorganizations are now a little more impactful.

It was getting to the point that the Pros outweight the Cons

Apart from moving some files around we made a few more tiny tweaks to
get this all working:

- Our freetext-filter component now performs the initial search rather
than this happening in the Controller (remove of the search method in
the Controllers and the new didInsertElement hook in the component)
- All of the <TabNav>'s were changed to use its alternative href
approach.
- <TabPanel>s usage was mostly removed. This is th thing I dislike the
most. I think this needs removing, but I'd also like to remove the HTML
it creates. You'll see that every new page is wrappe din the HTML for
the old <TabPanel>, this is to continue to use the same HTML structure
and id's as before to avoid making further changes to any CSS that might
use this and being able to target things during testing. We could have
also removed these here, but it would have meant a much larger changeset
and can just as easily be done at a later date.
- We made a new `tabgroup` page-object component, which is almost
identical to the previous `radiogroup` one and injected that instead
where needed during testing.

* Make sure we pick up indexed routes when nspaces are enabled

* Move session invalidation to the child (session) route

* Revert back to not using didInsertElement for updating the searching

This adds a way for the searchable to remember the last search result
instead, which changes less and stick to the previous method of
searching.

John Cowen c62b974222
ui: Fix using 'ui-like' KVs when using an empty default nspace (#7734)
When using namespaces, the 'default' namespace is a little special in
that we wanted the option for all our URLs to stay the same when using
namespaces if you are using the default namespace, with the option of
also being able to explicitly specify `~default` as a namespace.

In other words both `ui/services/service-name` and
`ui/~default/services/service-name` show the same thing.

This means that if you switch between OSS and Enterprise, all of your
URLs stay the same, but you can still specifically link to the default
namespace itself.

Our routing configuration is duplicated in order to achieve this:

```
- :dc
  - :service
  - :kv
    - :edit
- :nspace
  - :dc
    - :service
    - :kv
      - :edit
```

Secondly, ember routing resolves/matches routes in the order that you specify
them, unless, its seems, when using wildcard routes, like we do in the
KV area.

When not using the wildcard routes the above routing configuration
resolves/matches a `/dc-1/kv/service` to the `dc.kv.edit` route correctly
(dc:dc-1, kv:services), that route having been configured in a higher
priority than the nspace routes.

However when configured with wildcards (required in the KV area), note
the asterisk below:

```
- :dc
    :service
  - :kv
    - *edit
- :nspace
  - :dc
    - :service
    - :kv
      - *edit
```

Given something like `/dc-1/kv/services` the router instead matches the
`nspace.dc.service` (nspace:dc-1, dc:kv, service:services) route first even
though the `dc.kv.edit` route should still match first.
Changing the `dc.kv.edit` route back to use a non-wildcard route
(:edit instead of *edit), returns the router to match the routes in the
correct order.

In order to work around this, we catch any incorrectly matched routes
(those being directed to the nspace Route but not having a `~`
character in the nspace parameter), and then recalculate the correct
route name and parameters. Lastly we use this recalculated route to
direct the user/app to the correct route.

This route recalcation requires walking up the route to gather up all of
the required route parameters, and although this feels like something
that could already exist in ember, it doesn't seem to. We had already
done a lot of this work a while ago when implementing our `href-mut`
helper. This commit therefore repurposes that work slighlty and externalizes
it outside of the helper itself into a more usable util so we can import
it where we need it. Tests have been added before refactoring it down
to make the code easier to follow.

ui: Enable recovery from an unreachable datacenter (500 error) (#7404)
For URL maintenance reasons we store the last visited DC in
localStorage incase you come back to a page (for example settings) that
doesn't have a dc in the URL.

A problem arises here if the last DC you tried to visit is unreachable.

The first fix here clears out the last visited DC from localStorage if
the API has errored out.

Secondly, our `href-mut` helper which mutates the current current and
replaces 'parts' in the URL rather than the whole thing functioned by
detecting the current route/URL you are on an 'mutating' that. A problem
arose here as even though you might be on the `/ui/dc-1/services` URL the
actual route is the 'error' route which does not have a URL that can be
changed properly.

The second fix here uses route.currentRoute.name over route.currentRouteName.

The latter is equal to error when an error occurs whereas the former gives you the name of the route before the error happened, which is actually what we want/the intent here.

ie. when `router.currentRouteName === 'error'` then
`router.currentRoute.name === Name Of Route Before It Errored` it seems

ui: Gracefully cope with 500 errors from the disco-chain API endpoint (#7291)
When connect is disabled the discovery-chain endpoint returns a 500
error status, which we previoulsy did not gracefully cope with.

This commit gracefully copes with any errors from the disco-chain
endpoint by supressing the error and hiding the Routing tab from the
Service detail page.

Acceptance test included
