Hi @sbidoul, I rebased this PR on the latest 19.0, removed the temporary test-requirements.txt pointing to refs/pull/840/head, restored requirements.txt, and squashed everything into a single commit. CI is green on the new head.

Please do different PRs for queue_job_cron and queue_job_cron_jobrunner. Despite the similar name they are very different things.

Done: split as requested. This PR (#843) now contains only queue_job_cron. The queue_job_cron_jobrunner migration is in #876.
