Quartz: do we understand how this works: none of the neon-cluster-operator jobs are being triggered?

While testing https://github.com/nforgeio/neonCLOUD/issues/442 while running neon-cluster-operator locally on my workstation, I noticed that the related job class was not being executed.

I set breakpoints for all of the job class Execute() methods and manually edited the neonclusterjob resource to set all of the schedules to 0 1 * ? * * (once a minute). neon-cluster-operator reconciles the change and updates the job schedules just fine, but none of the breakpoints trigger after waiting 25 minutes.

I then tried restarting the operator again (in the debugger) and saw it reconcile the neonclusterjob resource but didn't see any of the breakpoints being hit after 10 minutes.

I'm not sure we understand how Quartz works. We should probably write some unit tests to investigate.

After we address this, we should follow up and complete these issues:
