We need a job service that allows:

• Independent job queues that can receive jobs.
  • Each queue should have configuration on job handling:
    • Time to allow before allowing another worker to take the job
    • Number of timeouts before considering the job a failure
    • How many completed jobs to retain
• APIs for:
  • enqueuing a job
  • await an executing job's result
  • dequeue a job
  • posting a job's result
  • query queue statuses
  • scheduling a job as a one-time or recurring job (cron)
• A mechanism to allow executable jobs to be registered from:
  • Backend
  • Collection
  • Schema
• Job queues should stop handing out jobs when the server is being shut down, and should block shutdown until jobs have finished.
• Closing and reopening a database should continue executing any pending jobs.
