Merge pull request #23344 from colemickens/azure-cluster

Automatic merge from submit-queue

azure: azkube v0.0.5 + deploy kube-system + hack/ script for hyperkube

Update the Azure bring up.

Also added a script `hack/dev-push-hyperkube.sh` for fast iteration on changes. One can deploy a cluster with a given hyperkube image reference and then use this script to rapidly iterate on changes. Testing changes just requires pulling the updated hyperkube image on the boxes and then cycling kubelet/docker or restarting the node.
