This extends the Kubelet to create and periodically update leases in a new kube-node-lease namespace. Based on [KEP-0009](https://github.com/kubernetes/community/blob/master/keps/sig-node/0009-node-heartbeat.md), these leases can be used as a node health signal, and will allow us to reduce the load caused by over-frequent node status reporting. - add NodeLease feature gate - add kube-node-lease system namespace for node leases - add Kubelet option for lease duration - add Kubelet-internal lease controller to create and update lease - add e2e test for NodeLease feature - modify node authorizer and node restriction admission controller to allow Kubelets access to corresponding leases |
