Proposed Changes
Removed the CNI iptables rules clean when an upgrade is done.
Unlike rules managed by the kubelet and kube-router, CNI rules are only created when the pod starts. If we remove them in the install script, networking to existing pods (such portmap rules for nodePort pods) will be broken.
