DNS service is a very critical service in k8s world, though it's not
a part of k8s itself. So it would be nice to have it replicate more
than 1 and on differents nodes to have high availbility. Otherwise,
services running on k8s cluster will be broken if the node contains
DNS pod down. Another sample is, when user would like to do a cluster
upgrade, services will be borken when the node containers DNS pod
being replaced. You can find lots of discussion about this, please
