WFLY-2382: adding default ee bindings to app client's java:comp
WFLY-2343: moving the ee concurrent interceptor up in the chain, to ensure it's not skipped
WFLY-2021 Change EE interceptors to be stateless

All state is now stored on the ComponentInstance, and can be setup during the post construct
phase. This largely removes the need for InterceptorFactory. At most a single instance of
each interceptor chain will be created per component, this should result in a massive decrease
in the amount of memory a component instance, and an instance reference allocates.
