Configure Mosquitto bridging with TLS

Configure Mosquitto bridging with TLS

The use-case for me is to connect my openHAB installation at our summer house with my production openHAB installation. The summer house openHAB instance will then just act as a slave to the production system and is connected using the MQTT binding and the MQTT Event Bus (Now replaced by the openHAB remote binding).

To be able to connect a remote Mosquitto instance to a central Mosquitto instance you need to configure the remote Mosquitto as a bridge and the central Mosquitto will then be the broker.
