k8sdemo: After node reboot, unable to deploy pods

[pkeerthana]

Restart a netplugin k8s node. After restart:
a) netplugin service is not started
b) firewall rules are not saved

After manual restart of netplugin service, below error is seen (possibly due to iptables rules not saved)

@rchirakk pls verify. If reproducible, open an issue in netplugin and close this one.
