This adds cluster tests for "kompose up" and "kompose down" for Kubernetes. At the moment this checks that they are deployable to a single-node Kubernetes cluster. More proficient tests such as testing if the pods are actually up will be added in the future. You can test this by running: `make test-ci` on your local-machine. Furthermore, we'll eventually have this enabled on Fabric8 / CentOS CI / Semaphore (whatever comes first) so we can have a full end-to-end testing environment.
