Hide Cloud Run on GKE behind a feature flag

See merge request gitlab-org/gitlab!19063

Currently creating a cluster using Cloud Run on
GKE results in a cluster that serverless
functions cannot be deployed to due to the issue
described in:
https://gitlab.com/gitlab-org/gitlabktl/issues/54

This hides the feature behind a feature flag until
that issue can be addressed in either gitlabktl or
upstream in the tm cli.

Align component version processing with omnibus

Closes #34873

See merge request gitlab-org/gitlab!19151

When we tag a release component version files are copied from GitLab
repository to Omnibus repository.

However the 2 process do not parse the file in the same way.

This commit ports omnibus logic into gitlab task_helpers

Remove links to doc/workflow and sunset readme

Closes #32940

See merge request gitlab-org/gitlab!19195

Because we already set the value to true in the previous migration, this
feature was switched on inadvertently in GitLab 12.4. This migration
toggles it back off to ensure we don't inadvertently block legitimate
users. The admin will have to re-enable it in the application settings.

In GitLab 11.0 (see
https://gitlab.com/gitlab-org/gitlab-foss/issues/40973 and
https://gitlab.com/gitlab-org/omnibus-gitlab/merge_requests/2237), we
disabled Rack Attack by default in Omnibus.

We inadvertently enabled by default in GitLab 12.4 via
https://gitlab.com/gitlab-org/gitlab/merge_requests/16463. This commit
introduces a database migration to restore the default to off.

This this doesn't touch the existing settings, so admins will have to
know to switch it off if they upgraded to GitLab 12.4.

Closes https://gitlab.com/gitlab-org/gitlab/issues/34212

his commit adds a new filter - "release" - to the issue search page.
This filter takes a tag name (i.e. v1.2) as a parameter and appends a
URL parameter to the search query like "release_tag=v1.2".

Use $CI_DEFAULT_BRANCH in CI templates

Closes #33601

See merge request gitlab-org/gitlab!18915

Since not every repository uses a branch named `master` as its default
branch, we've implemented the $CI_DEFAULT_BRANCH variable to allow us
to implement CI template logic for default branches of any name.

Now's the time to use that power in our own templates!
