Local MQTT Broker

In Earlier steps of the lab we introduced the local publisher and local subscriber concepts which allowed the Greengrass device to act as the data provider, however when the data provider resides outside of the Greengrass device a publish target can be introduced in the form of an MQTT Bridge turning the Greengrass device into an Local MQTT Gateway. This enables architectures that fit restricted network use-cases (such as with Industrial IoT environments) or local communications and processing as with Smart Home use cases.
