Draft: PK migration testing
This is not intended to get merged. It enables us to test the primary key migration changes on the testing pipeline. See gitlab-org/database-team/gitlab-com-database-testing!9 (closed) for the related changes there.
- This MR contains all relevant GitLab changes we'd like to test
- It also contains the WIP commit on top to strip CI down to one job
- This job triggers the testing pipeline
- The testing pipeline has a scheduler and an executor job
- The scheduler regularly enqueues new sidekiq jobs
- The executor picks up those jobs and executes them
