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. Change-Id: If36e9c26e2a8ebe622cfa7e9f2a07b1a69aabe34 Closes-Bug: #1555007
