Gwen Shapira commented on KAFKA-1772:
-------------------------------------
I think it makes sense, at least for "list" commands, to have one request and
one response that contains all the information above.
Actually, it may even make sense to just add the controller and consumers to
TopicMetadata request, which already contains topics and brokers.
> Add an Admin message type for request response
