btest/websocket/terminate-while-queueing: Use ZeroMQ

Browse source 
This adds a helper script to start the XPUB/XSUB proxy using the
XPUB_PORT and XSUB_PORT environment variables. The crux here is
that WebSocket clients go through the central XPUB/XSUB proxy.
This is different from Broker where WebSocket clients attach via
local hubs to the endpoint which doesn't require additional
configuration.
