background job handler (system checks, monitor, ..)

[vabene1111]

add some kind of background queuing system that can handle different tasks

• [ ] sync monitors (maybe with settings for auto import/timings)
• [ ] check for updates/configuration errors
• [ ] automatic backups

[vabene1111]

this appears to be either celery or django cron. Django cron is most likely best for the use cases needed here, celery seems a little op
