As part of https://gitlab.com/gitlab-org/gitlab-ce/issues/51716, we need
to remove 'experimental' labels from cluster views (show and form), as
well as the promp about cluster configuration, since it won't apply.

These changes were originally introduced on
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/22011/, but we're
trying to reduce the size of that MR as it's to big to review with
confidence.

Optimize merge request refresh by using the database to check commit SHAs

See merge request gitlab-org/gitlab-ce!22731

This allows us to use a kubectl binary that should be able to
connect to Kubernetes clusters v1.9 and up.

Use our own docker image for helm install pods

See merge request gitlab-org/gitlab-ce!22778

Previously for a given merge request, we would:

1. Create the array of commit SHAs involved in the push (A)
2. Request all merge request commits and map the SHA (B)
3. Reload the diff if there were any common commits between A and B

We can avoid additional database querying and overhead by
checking with the database whether the merge request contains any
of the commit SHAs.

Relates to https://gitlab.com/gitlab-org/gitlab-ce/issues/53213

Allows users to be fetched/created via the API.

This will reduce dependencies and failure points during installation. It
will also reduce security risks from untrusted dependencies being able
to effect all our users

the new gitlab-ui components.
