Kubernetes exploratory work to integrate the service broker

[nimakaviani]

The initial assumption is that we would be able to deploy the service broker as a POD to kubernetes and then have the service broker communicate with the kubernetes endpoints to deploy ethereum nodes as PODS.

This initial phase involves exploring the possibilities and figuring out problems, challenges that need to be addressed before we go after a proper TDD development model.

• the broker will need a config to know that it is running in 'direct access to docker' mode or 'kubernetes' mode

When it operates in kubernetes mode:

• the broker will need the config to access for kubernetes OR incluster-config. We can pull existing code from service-catalog.
• a namespace to run things in. OSBAPI may provide this as context-profile.

In theory, the image could be run Docker-in-Docker or DinD style, but this would result in all containers running in a giant container, and NOT spread across the cluster as would normally be expected.

since CFEE is k8s, this may be more relevant than we thought. I'll take a look.
