Retries in Sidekiq and in the remote mirror scheduler can cause repeated
attempts in quick succession if the sync fails. Each failure will then
send an e-mail to all project maintainers, which can spam users
unnecessarily.
Modify the logic to send one notification the first time the mirror
fails by setting `error_notification_sent` to `true` and reset the
flag after a successful sync.
Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/56222
From https://gitlab.com/gitlab-org/gitlab-ce/issues/53515, we see the
backend appears to have inconsistent default values for this column:
* DB schema: false by default
* UI checkbox: false by default
* `RemoteMirror` model: true by default
This leads to unintended behavior where the boolean is activated if the
UI doesn't pass in a value for the checkbox.
Cleanup code, and refactor tests that still use Rugged. After this, there should
be no Rugged code that access the instance's repositories on non-test
environments. There is still some rugged code for other tasks like the
repository import task, but since it doesn't access any repository storage path
it can stay.
Remote mirrors only get created when the URL changes, However, during the GCP
migration, the remote mirror did not get created automatically. Plus, there's
no guarantee someone restoring a repository from backup would have this
remote. We now add the remote each time we attempt to fetch from the
repository.
This works because Gitaly doesn't throw up an exception or error if the
remote already exists:

In the future, we should attempt to add if the remote doesn't exist:
