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
OK, so here I see its HTTP proxy, but yet we mention CSP specifically. This is going to be confusing to RHQ users because they are going to see these System Settings in the System Settinsg UI and not know what this CSP thing is all about. Is this a CSP-only settings? Or can we just use this as a generic HTTP proxy? If its CSP specific, we need to call it that ("CSP HTTP Proxy") and maybe even try to hide this if this is an RHQ build. I don't think we want RHQ users to see settings that are not applicable for RHQ builds.
