     * Step 1: Get Request Processor   
     *      A few ways to do this 
     *          - Extend RequestProcessor class and add required pre and post methods. Then inject instacne to construstor
     *          - Create RequestProcessorFactory to return RequestProcessor instnace with specific pre/post methods added
     *          
     * Step 2:
     *      Call ProcessRequestAsync method on processor and pass in actual action to perform
