How to enable Cross-Origin Resource Sharing (CORS) for RESTEasy service bindings in FSW 6

Issue

• We are developing an application based on FSW. The problem we have is that we cannot consume REST Services we are exposing from different origins.
• Our application consists of two main components: an AngularJS application and set of SwitchYard REST services. The front-end application (AngularJS) consumes the REST services we are exposing over SwitchYard. We have one service with a RESTEasy binding that exposes all the rest services.
• We tried with this community forum thread - "How to allow CORS" - but it didn't work. We tried to implement a web filter and a server interceptor, but neither worked.
