This class fetches all commits in a range in batches, selecting only
commits with a certain trailer set. This class will be used to fetch the
commits that should be used to generate a changelog.

This builds on the changes introduced in
https://gitlab.com/gitlab-org/gitaly/-/merge_requests/2842 and
https://gitlab.com/gitlab-org/gitaly/-/merge_requests/2999. To take
advantage of these changes, we also bump the Gitaly Gem version and add
fallback code for getting trailers using Rugged; as Rugged is still in
use. In addition, we change the merge_request_diff_commits table and the
MergeRequestDiffCommit model to support storing the trailers as JSON.

See https://gitlab.com/gitlab-com/gl-infra/delivery/-/issues/1365 for
more information.

Add auto-fix Label

See merge request gitlab-org/gitlab!50657

We need to assign a special label to identify bot's MRs

This is redundant with Rubocop's Style/FrozenStringLiteralComment cop,
which we didn't have enabled when this was introduced.

To preserve the same behaviour we also:

- Switch to `EnforcedStyle: always_true`, to forbid `false` values.
- Replace the wildcard list with an explicit list of all violations,
  so we still catch all newly added files.

Fix JS error on welcome page

The input field for "other" role only gets rendered when the feature
flag is active. Therefore we need to check if it exists when we receive
a `change` event on the select box.

We are experiencing performance issues with the merge request
refs cleanup functionality on production and some customers
instances. This became more visible when we started backfilling
`MergeRequest::CleanupSchedule` records for old merge requests.

Disabling the worker and scheduler for now behind a feature flag
so we can test the feature once we improve it's scheduling logic
before enabling it on other instances.
