v3.0.0b11 bugfixes

[roflcoopter]

This PR includes a multitude of fixes and changes to improve the stability of Viseron.
It also adds multiple clean up jobs to keep the database and filesystem in sync in case of any crashes.

Fixes

• Remove volumes from the Dockerfile to avoid issues with bind mounts
• Use the process watchdog for Darknet so that it is restarted in case of crashes
• Add extra logging to shutdown procedure to pinpoint threads and processes that is slowing it down
• Allow empty passwords for cameras
• Run every thread using RestartableThread so that it gets awaited during shutdown
• Fixes the move_on_shutdown: true config option. Previously Viseron did not wait for the callback to finish before exiting.
• A condition was missing when searchng for files for move_on_shutdown causing files to be moved multiple times
• Delete from FilesMeta table manually instead of using a trigger
• Properly throttle the function that checks if any files should be moved. This cause issues with attempting to move files multiple times
• Event clips are now generated in the servers timezone instead of UTC
