of service subnets.
Update DNS, Cert, dry-run logic to support list of Service CIDRs.
Added unit tests for GetKubernetesServiceCIDR and updated
GetDNSIP() unit test to inclue dual-sack cases.
This helper is used in tests and pulls in unnecessary dependency, which should
not be used if kubeadm is to move to staging.
Replace with direct use of the GroupResource type.

* fix duplicated imports of api/core/v1
* fix duplicated imports of client-go/kubernetes
* fix duplicated imports of rest code
* change import name to more reasonable
Used T.Run API for kubeadm tests in app/phases/*
This should improve testing output and make it more visible
which test is doing what.

Remove the deprecated `scheduler.alpha.kubernetes.io/critical-pod` pod annotation and use
the `priorityClassName` first class attribute instead, setting all master components to
`system-cluster-critical`.
As kube-dns transitioned to fat manifests, it's no longer required to use arch
suffixed images. This change makes use of fat manifests for kube-dns and
removes the last few calls to the GetGenericArchImage function, thus removing
GetGenericArchImage too.

When a Kubernetes cluster is instantiated in IPv6-only mode
via 'kubeadm init ...', the liveness probes that are
configured by kubeadm for kube-dns currently use IP:port
strings of "::1:53" and "::1:10053". These IP:port strings should
instead include brackets around the ::1 IPv6 loopback address, e.g.
"[::1]:53" and "[::1]:10053".
This change adds the necessary brackets around the ::1 IPv6 loopback
address.
Without this change, the kube-dns sidecar container interprets the
bracket-less strings as IPv4 IP:port strings that have too many
colons, and the kube-dns pod is restarted about once every 2 minutes.
