Change additional dnsmasq opts: - Adjust caching size and TTL - Disable resolve conf to not create loops - Change dnsPolicy to default (similarly to kubedns's dnsmasq). The ClusterFirst should not be used to not create loops - Disable negative NXDOMAIN replies to be cached - Make its very installation as optional step (enabled by default). If you don't want more than 3 DNS servers, including 1 for K8s, disable it. - Add docs and a drawing to clarify DNS setup. - Fix stdout logs for dnsmasq/kubedns app configs - Add missed notifies to resolvconf -u handler - Fix idempotency of resolvconf head file changes Signed-off-by: Bogdan Dobrelya <bdobrelia@mirantis.com>
