A simplified interface to MQTT.

More than a simple MQTT client implementation, it implements rooting a topic
tree, logging and retained topic retrieval.

Uses https://github.com/maruel/paho.mqtt.golang, a fork of
https://github.com/eclipse/paho.mqtt.golang that drops websocket support to
reduce the dependency set.
