Extend javax.interceptor.InvocationContext

Currently there is no easy way to obtain the interceptor binding annotation for an interceptor call. The interceptor binding annotation is needed to access @Nonbinding attributes and behave accordingly.

I propose to extend the javax.interceptor.InvocationContext interface with a method
public Annotation getInterceptorBinding() or
public <A extends Annotation> A getInterceptorBinding(Class<A> type)
The @AroundInvoke method of CDI Interceptors may use this extended interface as parameter instead of the original one to obtain the interceptor binding annotation.
