> ConsumeMQTT processor implements the MqttClient interface, which follows the
> signature of the Paho library's MqttClient interface. There are two issues
> with that. It mixes two types of behavior because the client itself can act
> as a publisher and subscriber parallelly. However, in NiFi, these two roles
> are separated into different processors. So it doesn't make sense to
> implement the subscribe interface in PublishMQTT, and it also doesn't make
> sense to implement deliveryComplete in ConsumeMQTT.
> The other issue is that these interfaces cannot be used with the HiveMQ
> client except messageArrived(). Because of the above, we need to move the
> existing implementation into the Paho adapter (because it is still required
> for logging) and create a new interface for handling incoming messages.
