Provide a sequence number on Requests which are added by the pipeline handler. Each pipeline handler keeps a requestSequence per CameraData and increments everytime a request is queued on that camera. The sequence number is associated with the Request and can be utilised for assisting with debugging, and printing the queueing sequence of in flight requests.
