This implementation is similar to AMQP notifications: * Notifications are published on a single topic as a JSON feed * Topic is configurable, as is the QoS. Uses the paho.mqtt.golang library for the mqtt connection, and supports connections over tcp and websockets, with optional secure tls support. * Additionally the minio server configuration has been bumped up so mqtt configuration can be added. * Configuration migration code is added with tests. MQTT is an ISO standard M2M/IoT messaging protocol and was originally designed for applications for limited bandwidth networks. Today it's use is growing in the IoT space.
