it's still works for our api, as non relevant properties does not shown in resource representation,
we using this concept all over the api.

both gluster and non gluster resources still be volumes so it's also works from the REST P.o.V.

i guess the question we should ask ourself if we really want to have collection peer technology
rather than differentiating between technologies by type.
