This is extracted from #8094, where I have run into some snags. Since
these ESLint fixes aren’t actually connected to the Ember 3.16 update
but involve changes to many files, we might as well address them
separately. Where possible I fixed the problems but in cases where
a fix seemed too involved, I added per-line or -file exceptions.
The UI will no longer try to redirect to the appropriate namespace or
region if one is found in localStorage. Instead, it will assume that
the lack of query param means the default namespaces or region is
desired.
This is incredibly tricky with query params, since there is a bundle of
timing issues, lifecycle issues, missing features, and all around
gotchas with query params.
This solution has no observers and no instances of the system service
being set from the jobs controller.
The upside to this is no observers, much easier to follow logic, no more
dependent key chain reactions.
