Squash project templates on update

See merge request gitlab-org/gitlab-ce!31592

As per https://gitlab.com/gitlab-org/gitlab-ce/issues/46043, project
templates should be squashed before updating, so that repositories
created from these templates don't include the full history of the
backing repository.

Migrations for Cycle Analytics backend

See merge request gitlab-org/gitlab-ce!31621

This change lays the foundation for customizable cycle analytics stages.
The main reason for the change is to extract the event definitions to
separate objects (start_event, end_event) so that it could be easily
customized later on.

This test was failing in EE because the API helper `get()` creates a
personal access token each time it's run. We can avoid that by
pre-creating a personal access token and passing it each time.

Only read rebase status from the model

See merge request gitlab-org/gitlab-ce!31847

Prior to 12.1, rebase status was looked up directly from Gitaly. In
https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/14417 , a DB
column was added to track the status instead. However, we couldn't stop
looking at the gitaly status immediately, since some rebases may been
running across the upgrade.

Now that we're in 12.3, it is safe to remove the direct-to-gitaly
lookup. This also happens to fix a 500 error that is seen when viewing
an MR for a fork where the source project has been removed.

We still look at the Gitaly status in the service, just in case Gitaly
and Sidekiq get out of sync - I assume this is possible, and it's a
relatively cheap check.

Since we atomically check and set `merge_requests.rebase_jid`, we
should never enqueue two `RebaseWorker` jobs in parallel.

Eliminate many Gitaly calls in discussions API

Closes #65957

See merge request gitlab-org/gitlab-ce!31834

Also adds comment to explain why this works on the diff-tab
when it's only used in `notes-app`.

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/30144#note_204066538

Previously, the API to retrieve discussions from merge requests often
generated hundreds of Gitaly calls to determine whether a system note
should be shown to the user. It did this by:

1. Rendering the Markdown
2. Extracting cross-references from the Markdown
3. For cross-references that were commits, a Gitaly FindCommit RPC
   would be issued to validate that the commit exists.

The last step is unnecessary because we don't need to display a commit
if the user doesn't have access to the project in the first place.

`RendersNotes#prepare_notes_for_rendering` is already used in
`MergeRequestsController`, which is why we don't see N+1 Gitaly calls
there. We use it here to optimize the note redaction process.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/65957
