NoOpCheckpointer is used in EventDataGeneratorStreamProvider ecosystem to replace the default Checkpointer which requires a back end storage. In EventHubDataGeneratorStreamProvider, it is generating EventData on the fly when receiver pull messages from the queue, which means it doesn't support recoverable stream, hence check pointing won't bring much value there. So a checkpointer with no ops should be enough.
