[pbs-devel] [PATCH v3 proxmox-backup 05/20] datastore: add helpers to check if snapshot/group is trash

[Christian Ebner]

The convenience helper method check for the trash marker file being
present within the snapshot/group directory. From the absence of the
marker file it may not be inferred that the snapshot/group is present
as regular item however.
