Problem: Experimental control not working on new top-nav menu, for example. changed App.supports.views/mirroring = true, redirected back to Ambari, the 'views' and 'mirroring' not show up on top-nav bar.
Reason: the whole experimental view is a lower level of the application controller which controlled the top-nav bar. So experimental control will not effect anything on the top-nav bar. This was not a problem before because the main menu not belong to top-nav before.
Solution: update the main menu on top-nav bar if there are changes in App.supports.
