[FAB-4516] Kafka-based Docker composition file

This docker composition file brings up a kafka-orderer
based fabric network. It includes a container that is
used as if it were a separate application.

Ideally, we would be able to use the python-sdk to make
these calls. This is a workaround, until that sdk is
ready.
