Proof of concept for vapor with zeromq
zeromq communication is done via swift-zmq (https://github.com/azawawi/swift-zmq)
if /zmq-request/{message} route is hit via GET request node connects via request interface issues a request command with message, the reply node (in this demo it is same node) echos message back to request node and after that message is returned to http client
zmq-reply-provider.json contains reply interface network config zmq-request-provider.json contains request interface network config
