Raise CoreDNS replica count to 2 or more

* Run at least two replicas of CoreDNS to better support rolling updates (previously, kube-dns had a pod nanny) * On multi-master clusters, set the CoreDNS replica count to match the number of masters (e.g. a 3-master cluster previously used replicas:1, now replicas:3) * Add AntiAffinity preferred rule to favor distributing CoreDNS pods across controller nodes nodes
