Sets a new delegate for receiving a message from the device queue using a cancellation token. After handling a received message, a client should call CompleteAsync(Message, CancellationToken), AbandonAsync(Message, CancellationToken), or RejectAsync(Message, CancellationToken), and then dispose the message. If a null delegate is passed, it will disable the callback triggered on receiving messages from the service.
