and also show the retention options that will be used for a given storage. A
user with Datastore.AllocateSpace and VM.Backup can already remove backups from
the GUI manually, so it shouldn't be a problem if they can set the remove flag
when starting a manual backup in the GUI.

Changes from v4:
    * Don't use gettext on a variable and use 'Keep Last' instead of
     'keep-last', etc. as labels.
    * Only show retention settings when the prune checkbox is set.
    * Do not hide zero/undefined retention options, now that there's more space
      with the two-column layout.
    * Use labelWidth 110 for retention options, so German (and maybe other)
      translations of labels do not wrap
