[pve-devel] [PATCH v2 proxmox-backup 08/10] manager: extend sync/pull completion

complete groups by scanning the remote store if available, and query the
sync job config if remote or remote-store is not given on the current
command-line (e.g., when updating a job config).

unfortunately groups already given on the current command line are not
passed to the completion helper, so we can't filter those out..

other filter types are completed statically.
