Update cluster-applications to v0.37.0

when adding a member to a project, now
correctly pass the namespace_id

This documents the use of /rebase for merge requests.

Also move rebase functionality into `MergeRequests::UpdateService` to
ensure merges/rebases are handled in the same location.

Since /rebase and /merge actions are not atomic, we may run into
confusing race conditions if these are applied together. For now, we
just ignore the /merge and proceed with the rebase.

This will make it easier for people to bring their merge requests
up-to-date.
