vNode MQTT Client will act a Publisher, Subscriber or writer.

In case of using Publisher feature to send data to any broker, vNode MQTT client module will publish the data based on 2 formats, the extended or the compact format. 

As far as now, vNode could not modify the payload structure in which it publish a message to an specific broker. It only can do it when it is configured as a Subscriber part, when pulling data from a Broker, and the payload format its not compatible with the one the uses vNode. 

This functionality will be added on the next module release over the 2nd quarter of the 2021.
