Adds utilities to speed up dev process (kubernetes-sigs#177)
cluster-api-dev-helper encodes a few common development tasks such as stand up and teardown within minikube, tailing logs etc... minikube_build adds a faster development experience by utilising the Docker endpoint in Minikube so images do not need to be pushed to an external repository.
