Do not backup if system is running on battery

[jose1711]

Maybe add an option to skip/postpone backup if system is running on battery (and battery level is under certain threshold)? Backup means IO and you may simply want to work longer than have a most-recent backup.

Do you know of a OS-independent way to get the current battery status? Else we would need different ways for each OS, similar to network or keychain.

psutil looks to be quite neat (https://psutil.readthedocs.io/en/latest/#psutil.sensors_battery) and seems to work fine on my laptop. Maybe this could be a new optional dependency. If the module is not present - the checkbox to toggle the option would be disabled.

We already use psutil to find existing Borg mounts. So this might be easy to add.
