I haven't reviewed everything in detail, but this approach looks
workable to me.

Of course, at the moment -object is a bit different from other options
in that it doesn't have a QAPI object for the options, but you just
directly pass QDicts to user_creatable_add_dict(). But plugging in a
visitor for other options groups doesn't suddenly require a different
design, so this is fine.
