neo4j-consumer: retry database connection on startup for one minute, maybe its taking longer. (retry, need to create a session for this)

neo4j-consumer: use one session instead of always opening one. add script to fill the mb with some swift data.

creating namespace within neo4j done. maybe not most efficient implementation, but we have experts for that.

rename neo4j compose container to neo, also change os.getenvironment code because links are no longer exported as environment variables (see https://docs.docker.com/compose/link-env-deprecated/)

implement a minimalistic kafka consumer to see whats coming into the messagebus. Create Dockerfile and docker-compose entry for it.

add docker-compose.yml creating a swift proxy with our middleware. At the same time create kafka/zookeeper cluster with kafka-manager webui.
