ozamiatin b5955b6ca9 [zmq] Redesign router proxy
In this change router was redesigned in a way most
appropriate for routing concept of zmq.ROUTER socket.

DEALER(cli)-ROUTER(proxy)-DEALER(srv) instead of
DEALER-ROUTER-DEALER-ROUTER (3 layers instead of 4)

The main reason is to use zmq.DEALER identity in message
routing. For this reason DealerConsumer was introduced
server-side. RouterConsumer is left for peer-to-peer
DEALER-ROUTER deployment option.

Also handled assertions in receive-methods in order
to not stop server when received message with wrong format.
