[pve-devel] partially-applied: [PATCH-SERIES v3] fix #4136: implement backup fleecing

[Fiona Ebner]

As discussed off-list with Thomas, applied the remaining non-RFC patches
and bumped the packages with the necessary dependency bumps. For the RFC
ones we'll have more time to decide upon the improved cleanup mechanism
(should it even go to the config or rather some file in /var) and minus
sign in config options.
