This PR adds trailing unit tests to check the service cluster IP range and improves the code coverage of k8s.io/kubernetes/cmd/kube-apiserver/app from 5.7% to 6.2%. 1) Dual stack IPv4/IPv6 2) Invalid IPv4, IPv6 mask 3) missing IPv4, IPv6 mask 4) invalid IP address format The tests 2, 3, 4 are suggsted by Antonio Ojea.
