[7.1] Configure Undertow as a Static Load Balancer Documentation is incorrect, sticky session does not work

The documentation [1] is incorrect, I have set up 7.1.0 as load balancer for two backend EAP server refer to the doc [1], but sticky session does not work. Here are the issues

• It specifies same instance-id to different backend server.
• It maps "/app" to reverse-proxy-handler but it does not match the acutal application context path. It should be "/test" in the guidance.

I have changed the setting to have different instance-id for backend server and changed the context root so they match, sticky session then works. I have written KCS [2] to reflect this.
