Show job status for timed out jobs as Failure

20:31:48 low: backup_job....
20:31:48.529350", "status": "Running"}
22:12:49 Killed horse pid 3060818
22:12:49 Moving job to FailedJobRegistry (Work-horse terminated unexpectedly; waitpid returned None; )

Possible Solutions

1. RQ should have a hook for this. after_job/failed_job/worker_killed etc.
2. We can peek in Redis to see if the job is running/pending, or is in the failed queue or not in any queue.
