[pbs-devel] [PATCH proxmox-backup 7/7] datastore: delete all objects on datastore destroy with remove data

[Christian Ebner]

If the user requested to delete a datastore, including all of the data,
also remove the objects from the s3 backend, if any.

This is limited to deleting objects within the datastore path prefix
within the bucket.
