ui: Don't default to the default namespace, use the token default namespace instead (#10503) 

The default namespace, and the tokens default namespace (or its origin namespace) is slightly more complicated than other things we deal with in the UI, there's plenty of info/docs on this that I've added in this PR.

Previously:

When a namespace was not specified in the URL, we used to default to the default namespace. When you logged in using a token we automatically forward you the namespace URL that your token originates from, so you are then using the namespace for your token by default. You can of course then edit the URL to remove the namespace portion, or perhaps revisit the UI at the root path with you token already set. In these latter cases we would show you information from the default namespace. So if you had no namespace segment/portion in the URL, we would assume default, perform actions against the default namespace and highlight the default namespace in the namespace selector menu. If you wanted to perform actions in your tokens origin namespace you would have to manually select it from the namespace selector menu.

This PR:

Now, when you have no namespace segment/portion in the URL, we use the token's origin namespace instead (and if you don't have a token, we then use the default namespace like it was previously)

Notes/thoughts:

I originally thought we were showing an incorrectly selected namespace in the namespace selector, but it also matched up with what we were doing with the API, so it was in fact correct. The issue was more that we weren't selecting the origin namespace of the token for the user when a namespace segment was omitted from the URL. Seeing as we automatically forward you to the tokens origin namespace when you log in, and we were correctly showing the namespace we were acting on when you had no namespace segment in the URL (in the previous case default), I'm not entirely sure how much of an issue this actually was.

This characteristic of namespace+token+namespace is a little weird and its easy to miss a subtlety or two so I tried to add some documentation in here for future me/someone else (including some in depth code comment around one of the API endpoints where this is very subtle and very hard to miss). I'm not the greatest at words, so would be great to get some edits there if it doesn't seem clear to folks.

The fact that we used to save your previous datacenter and namespace into local storage for reasons also meant the interaction here was slightly more complicated than it needed to be, so whilst we were here we rejigged things slightly to satisfy said reasons still but not use local storage (we try and grab the info from higher up). A lot of the related code here is from before we had our Routlets which I think could probably make all of this a lot less complicated, but I didn't want to do a wholesale replacement in this PR, we can save that for a separate PR on its own at some point.

# Significant patterns
## Ember specific
The Consul UI tries to follow typical conventional ember but differs
significantly in several places:
## Routing
### Routing
We use a declarative configuration format for our routing rather than Ember's
DSL. The format is closely modeled on Ember's DSL and if you need to generate
Ember's DSL from this for some reason you can use one of our Debug Utilities
to do this.
## Routes

functionality for several important additions. If you use the normal `ember

Please see our package.json file dependencies.
## Consul specific
### Namespace support
Whilst Consul namespaces are a OSS feature of Consul, we almost always build
things 'pretending' that namespaces are always enabled. Then there is code
within the data layer of the application that removes any namespace related
query parameters.
Namespaces are a little more complex to think about than other things in
Consul as we have the idea of 'the default' namespace, and then additionally
an ACL token can have 'a default' namespace (not the same as 'the default'
namespace) which is a little like a namespace that is assigned to the token,
or where the token originated from. The Consul backend can then use the tokens
default/origin/assigned namespace to figure out whether and how to filter any
results by namespace before sending those results to the UI.
When you are requesting data from the API you should always include a
namespace (if applicable to the API endpoint), but you should never default
the namespace value to 'the default' namespace - `default`. Conversly, when
receiving data from an API response, there are some places where we do default
a namespace to 'the default' namespace `default`. The easiest way to think
about this is: If its on the way out, don't add a default ever, if its on the
way in you may need to default any potentially empty Namespace parameters to
`default` (due to using Consul without namespaces enabled), there is a
NspaceAbility and/or an `env` feature flag to help you to discover this.
We've made various decisions in the UI to make it hard to omit a namespace
when you shouldn't, for example using our DataSource component requires you to
include a defined namespace parameter (even if the value for that is `''`),
and the route parameter `nspace` value will always default to `''`. It also
reminds you to be continually thinking about namespaces whilst adding new
features.
Lastly, we always refer to namespaces in code as the word `nspace` or
`nspaces`. Both `ns` and `namespace` have other purposes in Ember and Ember
Data (in various places one is significant but not the other and vice versa).
Always using the term `nspace` means we avoid any strange bugs or
clashes/overwrites with anything in Ember or Ember Data core. The only place
where we use `ns` or `Namespace` is to construct API requests/responses.
Sometimes when using this term in CSS or on plain javascript objects, this may
seem unnecessary but it just helps smooth over writing code around namespaces
as you don't have the split second decision of whether you write `ns` or
`namespace` - just use `nspace` and everything will be fine :)
