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
Server would return 404 - because we require /rha/support.html. I'll fix this so it behaves exactly same as if you just go to any other unexisting page (i.e. coregui/#Foo)
