the Node object annotation: ‘net.beta.kubernetes.io/proxy-mode’. If the
annotation is not specified, then ‘iptables’ mode is the default. If kube-proxy
is unable to start in iptables mode because system requirements are not met
(kernel or iptables versions are insufficient), the kube-proxy will fall-back
to userspace mode. Kube-proxy is much more performant and less
resource-intensive in ‘iptables’ mode.

- Revised the logic for `DaemonSet` rolling update to exclude nodes if scheduling constraints are not met. This eliminates the problem of rolling updates to a `DaemonSet` getting stuck around tolerations.
