Example for connecting and maintining a connection with a STOMP websocket connection.
In this example, we connect to a Spring application (see https://docs.spring.io/spring/docs/current/spring-framework-reference/html/websocket.html).
In particular, we use the default STOMP WebSocket example by Spring: https://github.com/spring-guides/gs-messaging-stomp-websocket
That is, we connect to the Spring server, send a "hello" and get back a "greeting".
