> VerifiableProducer should do a clean shutdown in stop_node()

> VerifiableProducer is closed by SIGKILL when stop_node() is called. For this
> reason, when stop_producer_and_consumer() is invoked in
> ProduceConsumeValidateTest, VerifiableProducer is killed immediately without
> allowing it to wait for acknowledgement. The reported number of messages
> produced by VerifiableProducer will thus be much smaller than the reported
> number of messages consumed by consumer, causing confusion to developers.
> For almost all other services, such as VerifiableConsumer and
> ConsoleConsumer, we send SIGINT when stop_node() is called. It is not clear
> why VerifiableProducer is different from them.
