MQTT support

The payload is formatted in JSON notation. The measurement reference is the Unix date/time in milliseconds.

Currently only the weight of an user is transmitted. You could test the openScale sync MQTT support for example using CloudMQTT.

Note: openScale supports only MQTT 3.1 not MQTT 5.x
