Kubernetes Version Compatibility

The daemon image contains a 1.22.x k8s.io/{client-go,kubectl} for the purposes of maintaining the lock and draining worker nodes. Kubernetes aims to provide forwards & backwards compatibility of one minor version between client and server, so this should work on 1.21.x, 1.22.x and 1.23.x
