I am getting notifications for push events - however, pipeline jobs notifications are not working. ## Proposal Some notifications are rate-limited, which we currently don't handle: https://gitlab.com/gitlab-org/gitlab/-/issues/356896#note_934257676 To fix this I think we would need to reschedule the failed `ProjectServiceWorker` job, using `retry_after` from the response (which might be minutes or seconds).
