Daniel Tschlatscher c3e2ff806f fix #3972: Remove the .notes file when a backup is deleted
When a VM or Container backup was deleted, the .notes file was not
removed, therefore, over time the dump folder would get polluted with
notes for backups that no longer existed. As backup names contain a
timestamp and as the notes cannot be reused because of this, I think
it is safe to just delete them just like we do with the .log file.

Furthermore, I sourced the deletion of the log and notes file into a
new function called "archive_auxiliaries_remove". Additionally, the
archive_info object now returns one more field containing the name of
the notes file. The test cases have to be adapted to expect this new
value as the package will not compile otherwise.
