Ensure dnsmasq is restarted during upgrades

[michaelgugino]

Currently, upgrades are failing because sdn pod
does not notify dnsmasq to update dns server list.

This commit ensures dnsmasq is restarted before docker
is restarted so static pods get valid networking.

This shouldn't be necessary but no harm should come of it since if the SDN pod is working properly it will repopulate dnsmasq config after 30 seconds.
