code: @Override
      public final Result call(Route route, RequestContext context) throws Exception {
          return call(context.getConfigurationForInterceptor(this), context);
      }
docs: The interception method. The method should call {@link org.wisdom.api.interception.RequestContext#proceed()}
  to call the next interceptor. Without this call it cuts the chain.
  
  @param route the route
  @param context the filter context
  @return the result
  @throws Exception if anything bad happen
