[pbs-devel] [PATCH v3 proxmox-backup 3/3] fix #4374: create a prune job upon datastore creation

creates a default prune job if prune-schedule is set when creating the
datastore.

Auto generates a name for a prune-job with a truncated uuid to avoid
collisions.

Prune settings were stored in the datastore config but have no effect.
Prune settings are not stored there anymore
