MQTT
MQTT outputs are able to connect to an MQTT broker. The endpoint must be
formatted as tcp://<host>:<port> for unencrypted connections or
ssl://<host>:<port> for TLS connections. TLS connections is highly
recommended. If you use a self-signed certificate you can disable the
certificate check by setting the check flag in the configuration.
The host name must be valid and reachable. The port must always be included in the endpoint.
The payload is a JSON structure (the IDs and metadata might be different depending on the device, collection and payload):
