Add STOMP client
WebSocketStompClient can be used with any implementation of org.springframework.web.socket.client.WebSocketClient, which includes org.springframework.web.socket.sockjs.client.SockJsClient. Reactor11TcpStompClient can be used with reactor-net and provides STOMP over TCP. It's also possible to adapt other WebSocket and TCP client libraries (see StompClientSupport for more details). For example usage see WebSocketStompClientIntegrationTests. Issue: SPR-11588
