    [zmq] Reduce number of connections

    In this change 'use_router_proxy' option was added
    to switch between direct connections and proxy.

    Proxy was reimplemented and splitted onto two
    types of proxies:

        * PUBLISHER proxy for fanout pattern
        * ROUTER proxy for direct messaging

    Each type of proxy is configured over command line
    argument --type.

    Deployment guide was updated accordingly to the change.
