[pbs-devel] [PATCH proxmox-backup 1/2] tape: ui: TapeRestore: make datastore mapping selectable

[Dominik Csapak <d.csapak@proxmox.com>]

by adding a custom field (grid) where the user can select
a target datastore for each source datastore on tape

if we have not loaded the content of the media set yet,
we have to load it on window open to get the list of datastores
on the tape
