Support KUBERNETES_MASTER env variable

[marquiz]

Support (insecure) connections to the Kubernetes API server by setting the KUBERNETES_MASTER environment variable. This is how e.g. kubectl behaves and also matches the error message(s) from client-go package. This patch is targeted for local testing and development.
