reuse-datastore: avoid creating another prune job

If a datastore with a prune job is removed, the prune job is preserverd
as it is stored in /etc/proxmox-backup/prune.cfg. We also create a
default prune job for every datastore – this means that when reusing a
datastore that previously existed, you end up with duplicate prune jobs.
To avoid this we check if a prune job already exists, and when it does,
we refrain from creating the default one. (We also check if specific
keep-options have been added, if yes, then we create the job
nevertheless.)
