[CD16][DOCS] EAP 7.2/7.3 Configuring Messaging doc may include incorrect tech preview note

Reported by ibodunov through the middleware-docs Google Hangout chat 25-Feb-2019:

"In EAP 7.1.3 "EJB and JNDI over HTTP/HTTPS with HTTP Load Balancer" was in Tech Preview. In EAP 7.2 it is fully supported, as visible from the Release Notes. But in "Configuring Messaging" doc it still says that "JNDI Lookup Behind the Load Balancer Is Provided as Technology Preview Only". Can someone clarify this?"

It is likely that the 7.2 Release Notes is correct, and that the "Configuring Messaging" doc requires a change to remove the Tech Preview only mention.

Please double-check this and make the change in the 7.2 guide if needed. If the change is made to the 7.2 guide, please also make the same change to the current CD version/EAP 7.3 guide version.
