Handfull of updates to make the script play nicely with Kubernetes v1.10: Bumps the K8S version in the README. Updates to latest Ubuntu LTS (image from the original script no longer exists). Updates the admission-control passed to the API server to v1.10 recommended defaults. Takes advantage of native support in kubeadm to not taint the master node. Grabs the latest Calico recommended in the kubeadm docs.
Ubuntu-1704 family is deprecated at GCE now Also the default kubernetes version for the latest 1710 ubuntu is 1.9
Add section to 20-cloud-provider.conf to ensure kubelet gets cloud provider configured. Without this things like storage classes and persistent volume claims do not work.
