Get the price, the WebSocket way

The WebSocket endpoint is deployed on /<application_context>/quote, and some exchanges can look like the following:

connect> ws://localhost:9090/quote-manager/quote
send> {"name":"VNET"}
received< {"found":true,"value":5.19}
send> {"name":"DDD"}
received< {"found":true,"value":12.56}
disconnect>
Connection closed: Close status 1000 (Normal Closure)

What is interesting to see in this communication dump is the fact that the connection lasts for more than one request, and it is based on the symbol more than the identifier (compared to the previous JAX-RS samples).
