v2 of the series, some small parts are still in-progress/unfinished:
* api path is (imho) not optimal, but did not find something better
  (integration into existing restore call gets ugly fast...)
* schema for the snapshot list is not done yet (but not hard..)
* gui for multiselection is not done yet (have to think about how
  we do that for a good ux)

questions still to answer:
 do we really want to have the ability to restore multiple 'single' snapshots
 in one go? if not, it would drastically simplify the code

changes from v1:
* use parallel handler for chunk restore
* rebase on master
* add patch to return manifest from try_restore_snapshot_archive
* using of Arc<WorkerTask> like we do now in rest of the file

@Dietmar, could you test on real tape hardware if it works correctly as-is?

Dominik Csapak (8):
  tape/drive: add 'move_to_file' to TapeDriver trait
  tape/media_catalog: add helpers to look for snapshot/chunk files
  api2/tape/restore: factor out check_datastore_privs
  api2/tape/restore: remove unnecessary params from
    (try_)restore_snapshot_archive
  api2/tape/restore: return backup manifest in
    try_restore_snapshot_archive
  api2/tape/restore: add 'restore-single' api path
  bin/proxmox-tape: add restore-single command to proxmox-tape
  ui: tape: add single snapshot restore
