Tests: Make e2e test platform-agnostic
The test:
[k8s.io] Pods should support remote command execution over websockets [NodeConformance]
uses cat on /etc/resolv.conf and checks if the output from the container is "namespace",
which is incompatible with windows containers as there is no such file.
Since the test just check if remote command execution works, the command is
irrelevant as long as the output checks out. Switched to using echo "remote execution test",
and checking that output as it works for both windows and linux.

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
