Implements KEP 2000, Graceful Node Shutdown: https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/2000-graceful-node-shutdown * Add new FeatureGate `GracefulNodeShutdown` to control enabling/disabling the feature * Add two new KubeletConfiguration options * `ShutdownGracePeriod` and `ShutdownGracePeriodCriticalPods` * Add new package, `nodeshutdown` that implements the Node shutdown manager * The node shutdown manager uses the systemd inhibit package, to create an system inhibitor, monitor for node shutdown events, and gracefully terminate pods upon a node shutdown.
