Add --delete-volume and --delete-volume-full

Browse Source 
--delete-volume <name> removes a volume's config entry only.
--delete-volume-full <name> also recursively deletes its host
directory -- fails before touching the config if that deletion errors,
so a failed directory delete never silently drops the config entry;
warns instead of failing if the directory was already gone.

Both are long-only, following the --list-volumes precedent, and slot
into the existing multi-mode getopt dispatch the same way -v/--volume
already does.
