[pbs-devel] [RFC v2 proxmox-backup 09/21] datastore: refactor recursive namespace removal

[Christian Ebner]

Split off the recursive destruction logic for the namespace folder
hierarchy into its own helper function.
This will allow to separate the marking of namespaces as trashed
from the actually destruction an namespace cleanup by garbage
collection or when bypassing the trash.
