Support MQTT gateway about mycontroller-v1-legacy HOT 2 CLOSED

FYI there are two different MQTT gateways right now. The version in MySensors 1.5 is a pseudo-broker (i.e. a broker with an extremely limited feature set). There is another version which is an MQTT client (I believe the latest version is https://github.com/ntruchsess/MySensors/tree/mqttclient). The difference is that the client publishes messages to an existing broker. The pseudo-broker allows a limited number (might be only 1, not sure) of connections and publishes all messages to those connections.

Anyone using MQTT is running a broker (Mosquitto, RabbitMQ, etc) so, in my opinion, the MQTT client gateway version is a much better version to support. In that mode, MyController would just implement a basic MQTT publish/subscribe model with a broker and the broker will take care of routing to the gateway. Of course since the other gateway is a broker, that might not be a big difference. But I'm not sure if they use exactly the same message structure or not - that would have to be checked.

For now I have added support for https://github.com/mysensors/Arduino/tree/master/libraries/MySensors/examples/MQTTGateway But it has very limited support, We have to change address(topic) format to support all the available MysSensors commands.
