Added scripts to automate setting up cluster
Scripts support custom number of controllers and workers as well as a specific version of Kubernetes by exporting NUM_CONTROLLERS, NUM_WORKERS, and KUBERNETES_VERSION respectively. This has only been tested using 3 controllers and workers >= 3 using Kubernetes version 1.5.1.pull/118/head
