Borg handler compatibility with borg 1.2
Current borg handler is not fully compatible with borg 1.2.
- New warnings can cause a lot of noise (https://github.com/borgbackup/borg/issues/6379).
- We need to explicitly call
borg compact
(https://borgbackup.readthedocs.io/en/stable/usage/notes.html#separate-compaction)
I am working on a new version of the handler. I will submit my changes when they are well tested.
