This commit imports the latest development focus from the Charmer team working to deliver Kubernetes charms with Juju. Notable Changes: - The charm is now assembled from layers in $JUJU_ROOT/layers - Prior, the juju provider would compile and fat-pack the charms, this new approach delivers the entirety of Kubernetes via hyperkube. - Adds Kubedns as part of `cluster/kube-up.sh` and verification - Removes the hard-coded port 8080 for the Kubernetes Master - Includes TLS validation - Validates kubernetes config from leader charm - Targets Juju 2.0 commands
