Add partial response and env vars

Cluster create will return a partial response (missing status and pods).
Additionally, the following env vars are used and must be set:

OSHIKO_CLUSTER_NAMESPACE (the project to run in)
OSHINKO_KUBE_CONFIG (the path to a .kube/config file, must have a logged in user)
OSHINKO_CLUSTER_IMAGE (the tag of the image to use, ex 172.30.122.181:5000/spark/openshift-spark)
