The `k8s-reboot-coordinator` coordinates node reboots throughout the cluster. It runs as a DaemonSet, watching for the presence of a sentinel file, `/run/reboot-needed` on the node. When the file appears, it acquires a lease, to ensure that only one node reboots at a time, cordons and drains the node, and then triggers the reboot by running a command on the host. After the node has rebooted, the daemon will release the lock and uncordon the node.
