Add basic GraphQL for a Group

Closes #60786

Due to the nature of pipelines for merge requests, deployments.ref can
be a merge request ref instead of a branch name.

We support the environment auto-stop hook for this case

Refactor LfsImportService and ImportService

Uninstall cluster applications (backend services)

Closes #60665

See merge request gitlab-org/gitlab-ce!27096

These builder methods are using user provided input inside a public_send
but this is safe to do in this instance because before they are called
we check before calling them that they match an expected application
name.

In order to not miss any errors since we are not checking the return
value of update

Basically does the reverse of after_transition to :installed.

Add endpoint to delete/uninstall a cluster application

Add specs

Only prometheus can be uninstalled atm, the rest will be dealt with
later.

Presumption is that new application types will have uninstallation
implmemented at the same time.

Rescue and put into :uninstall_errored if something goes wrong while
destroying, which can happen. I think it is safe to expose the full
error message from the destroy error.

Remove the :uninstalled state as no longer used.
