Docs: Changing badges to use parentheses not brackets

See merge request gitlab-org/gitlab-ce!30439

Previously, we used brackets to denote the tier badges,
but this made Kramdown, the docs site Markdown renderer,
show many warnings when building the site. This is now
fixed by using parentheses instead of square brackets.

This was caused by [PREMIUM] looking like a link to
Kramdown, which couldn't find a URL there.

however, this causes a race condition that it can be
overwritten by CheckMergeabilityService.

This patch fixes the problem by generating `refs/train`
for those pipelines.

Clusters hierarchy CTE

See merge request gitlab-org/gitlab-ce!30063

- This enables us to use a scope to query all clusters in group
hierarchy order in one query, and also enables us to union to instance
clusters later.

- Handle case where clusters not present at level. In which case the
query should go ahead and return the next level's clusters.

- Swap with new CTE query behind Feature flag. This FF is default
disabled.

Also memoize has_metrics? as well, that might be expensive, and it
should not change for the lifetime of EnvironmentStatus

In 12.2 we will remove this fallback.

We stopped calling the fallback so we can remove this now

Split into followup issue

We can now share project so that we don't have to load project twice.
Also, this extracts non-relevant logic out of Deployment.

Update DeploymentsController accordingly

Otherwise, each EnvironmentStatus object instantiates its own project
when really they are the same. Improves query count performance
