v4 of the series, should be an ok and working state, nothing
obvious is missing or not working besides
* gui for multiselection (i have some ideas, but we can allow
  single snapshots for now and add multiselect later)

changes from v3:
* split the refactoring of the 'restore_worker' into its own patch
* renamed 'restore_worker' to 'restore_full_worker' and
  'restore_single_worker' to 'restore_list_worker' (hopefully those
  names are clearer?)
* rebased on master

changes from v2:
* added schema for snapshot
* integrated with the normal restore api call and command
* added completion helper for proxmox-tape
* added small api-viewer patch to improve the '<array>' type text
* rebase on master

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

and create the 'email' and 'restore_owner' variable at the beginning,
so that we can reuse them and do not have to pass the sources of those
through too many functions

From: Dominik Csapak @ 2021-05-10  9:27 UTC (permalink / raw)
  To: pbs-devel

this makes it possible to only restore some snapshots from a tape media-set
instead of the whole. If the user selects only a small part, this will
probably be faster (and definitely uses less space on the target
datastores).

the user has to provide a list of snapshots to restore in the form of
'store:type/group/id'
e.g. 'mystore:ct/100/2021-01-01T00:00:00Z'

we achieve this by first restoring the index to a temp dir, retrieving
a list of chunks, and using the catalog, we generate a list of
media/files that we need to (partially) restore.

finally, we copy the snapshots to the correct dir in the datastore,
and clean up the temp dir
