[pve-devel] [PATCH storage] Remove the .notes file when a backup is deleted

[Fabian Ebner]

Commit title should include "fixes #3972"

Please note that there's also an archive_remove() function in Storage.pm
which is called when pruning. That (and I'd say archive_info() too)
should be extended to also handle the notes file.

Nit: should be "VM or Container backup"

It would be nice if we could simply switch to calling archive_remove()
here for non-PBS, but that might break interaction with external
plugins. But maybe we can at least re-use archive_info() to match the
path and get the log and notes file names.
