Snapshot cleanup did not work due to time.Now syntax error. Added test
for it as well to catch any future errors.
Added error and debug logging so that it is possible to see any errors in the future.
Removed an unused configuration value and deprecated the remove expired snapshots
setting.
Admins can see all snapshots. Other roles can only see their own
snapshots.
Added permission check for deleting snapshots - admins can delete
any snapshot, other roles can delete their own snapshots or
snapshots that they have access to via dashboard permissions.
