Controls passed to Camera::start() are not handled at the moment. Implement that by issuing a dummy queueRequest() to initialize the frame context and then returning the controls synchronously to the caller. In the pipeline the controls get passed to the sensor before the call to stremOn() to ensure the controls are applied right away. Passing the controls to the pipeline using the setSensorControls signal is not appropriate because it is asynchronous and would reach the sensor too late (initial controls need to be applied before the sensor starts and before delayed controls initializes it's start condition.)
