How to handle missed scheduled jobs?

[llamafilm]

If a job is scheduled to run while Netbox is not running, it will run immediately after Netbox starts again. This can cause problems in some scenarios, but I suppose it would be desirable in others. So I'm not sure of the best way to handle this. Maybe we need a checkbox to choose this behavior when creating a scheduled job?

In this case, I want to power cycle a PDU outlet weekly, for a device that gets buggy after running a long time. I schedule it to happen in the middle of the night when nobody is around. Suppose Netbox crashes and it misses this interval. The next day I fix the problem and restart Netbox. Now the power outlet will cycle during business hours, which is disruptive.

An easy way to reproduce this behavior:

1. Schedule a script to run every 5 minutes
2. Stop the Netbox service at 14:31 (systemctl stop netbox netbox-rq)
3. Wait 11 minutes, then restart Netbox service at 14:42 (systemctl start netbox netbox-rq)
4. Observe that the job ran twice at 14:42, and then again at its correct interval of 14:45.
