For the GWT to Angular work, several JSPs and Controllers are going to be deprecated.
Currently, the controller behind "KSC/index.htm" (i.e. org.opennms.web.controller.ksc.IndexController) is the responsible for reloading the KSC configuration.
I think we can move this functionality to the ReST API for KSC. That way, we can use Angular's $http to reload the configuration.
