[pve-devel] [PATCH v3 manager 4/4] fix #2745: ui: backup: allow specifying remove parameter for manual backup

[Fabian Ebner]

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 v2:
    * hide Prune checkbox if there are no prune-settings or if keep-all=1
    * also show the retention options that are going to be used
