we have 2 modi in that window:
* backup has multiple datastores
* backup has single datastore
In the first case we show a 'mapping' grid so that
the user can only restore a part. Here a user sees all source
Datastores and can select a target for each one.
In the second case we only have a single 'Datastore' selector, but
we do not show the source. Because of this, the naming is slightly ambiguous
(is it the 'Source' or the 'Target' ?), so rename it to 'Target Datastore'.

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

so that the tape backup can be restored as any user, given
the current logged in user has the correct permission.
