Create a reference architecture and example function that allows Greengrass to stream data from a local AMQP server to a Lambda function

[timmattison]

Many customers and partners have systems that gather data and can feed that data to external systems by multiple mechanisms (REST, AMQP, etc). REST polling is convenient but not efficient for high velocity data streams. An example function that can act as a configurable AMQP client, relay the data to a Lambda function, and republish that data to AWS IoT Core would be useful.
