      Description

      Currently the module automatically does this step. If a publish with qos1/2 is received, we send back the puback/pubrel.

      Especially for qos2 that might be dangerous as finalizing a qos2 message can imply that it has been processed and all requirements containing that message are met. One use case is payment via a qos2 message. You have to ensure that the transaction is done and then puback.

      Hence, add an API which allows to enable manual release of a message.

       

      This is even more important in MQTT 5.0 where you can specify the maximum of "open" messages before the broker starts sending a new one (batch messages).
