JON 3-11 and JON 3-12

This PR adds support for CSP (or RH Access) integration to JON.

New WAR subdeployment called rh-access-war is a standalone application that provides integration between JON and RHA. It conains anuglar app provided by RHA team and simple backend sevlet that get's called in case customer wants to attach JON JDR Report when opening support case.

Integration to coregui is done by HTMLPane (IFRAME). This Page is accessible from Help main menu (Product section) and also from main bar (next to message center icon)

This PR implements JON 3-11 - option for users to open JON support case and 3-12 - option for users to open support case on EAPs managed by JON.

This PR is ready for merge - RHA support is disabled in UI and build by default, can be enabled via enable-rha maven profile
These settings are used by RHA support java lib (haven't tried 'though), will be also used as a default/fallback by jboss-software server plugin. So it is kind of general proxy settings.

I wanted to mention CSP (or something like that) to aviod possible confusion, when people can think, that this proxy can be used for server->agent communication.


@metlos I'll fix jboss-sofware to take advantage of this global settings, once it's in master

ok .. I'll replace CSP keywords with nothing
