[keycloak-user] 1.1 documentation update for running in domain HA mode

Hi guys, Thanks so much for getting clustering support working in 1.1. I have it up and running well in a Wildfly 8 domain setup under the "full-ha" profile. One thing that I was pulling my hair out about for a while today were some errors related to Infinispan config. I figured out that if running in HA cluster, you must include the "transport" element under the cache-container config (i.e. <transport lock-timeout="60000" />). It would be great if you could update Chapter 23 of the documentation to reflect this requirement. Thanks, John
