* Add a var for ndots (default 5) and put it hosts' /etc/resolv.conf. * Poke kube dns container image to v1.7 * In order to apply changes to kubelet, notify it to be restarted on changes made to /etc/resolv.conf. Ignore errors as the kubelet may yet to be present up to the moment of the notification being processed. * Remove unnecessary kubelet restart for master role as the node role ensures it is up and running. Notify master static pods waiters for apiserver, scheduler, controller-manager instead. Signed-off-by: Bogdan Dobrelya <bdobrelia@mirantis.com>
