kubeadm: Fully implement --dry-run

**What this PR does / why we need it**:

Finishes the work begun in #50631 
 - Implements dry-run functionality for phases certs/kubeconfig/controlplane/etcd as well by making the outDir configurable
 - Prints the controlplane manifests to stdout, but not the certs/kubeconfig files due to the sensitive nature. However, kubeadm outputs the directory to go and look in for those.
 - Fixes a small yaml marshal error where `apiVersion` and `kind` wasn't printed earlier.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #

fixes: https://github.com/kubernetes/kubeadm/issues/389

**Special notes for your reviewer**:

Full `kubeadm init --dry-run` output:

Your Kubernetes master has initialized successfully!

To start using your cluster, you need to run (as a regular user):

  mkdir -p $HOME/.kube
  sudo cp -i /tmp/kubeadm-init-dryrun477531930/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  http://kubernetes.io/docs/admin/addons/

You can now join any number of machines by running the following on each node
as root:

  kubeadm join --token 96efd6.98bbb2f4603c026b 192.168.200.101:6443 --discovery-token-ca-cert-hash sha256:ccb794198ae65cb3c9e997be510c18023e0e9e064225a588997b9e6c64ebf9f1

3390bc3cbc Updates Kubeadm Master Endpoint for IPv6
Previously, kubeadm would use <ip>:<port> to construct a master
endpoint. This works fine for IPv4 addresses, but not for IPv6.
IPv6 requires the ip to be encased in brackets when being joined
to a port with a colon.

This patch updates kubeadm to support wrapping a v6 address with
[] to form the master endpoint url. Since this functionality is
needed in multiple areas, a dedicated util function was created.

Fixes: https://github.com/kubernetes/kubernetes/issues/48227

2dd359ba19 kubeadm: add pubkeypin package (public key pinning hash implementation).
This change adds a `k8s.io/kubernetes/cmd/kubeadm/app/util/pubkeypin` package which implements x509 public key pinning in the style of RFC7469. This is the public key hash format used by the new `kubeadm join --discovery-token-ca-cert-hash` flag.

Hashes are namespaced with a short type, with "sha256" being the only currently-supported format. Type "sha256" is a hex-encoded SHA-256 hash over the Subject Public Key Info (SPKI) object in DER-encoded ASN.1.

kubeadm: Remove the old KubernetesDir envparam

**What this PR does / why we need it**:

The last piece of https://github.com/kubernetes/kubernetes/issues/48053 for moving the env params into the API, and the KubernetesDir into a constant.

After this pretty mechanical change, we might offer short-hand functions in constants like `GetStaticPodManifestDir()` etc easily in order to centralize the `filepath.Join` logic into one place.

kubeadm: Allows to use versions like 1.6.4 instead v1.6.4

**What this PR does / why we need it**:

As part of issue kubernetes/kubeadm#292 discussion, it
turned out that for users it is not always obvious that
version specification parameter must be in form "vX.Y.Z".
This patch allows to specify it in form "X.Y.Z" and
converts it internally to normal semantic version which
expected in the rest of the code.

**Special notes for your reviewer**:

**Release note**:

```release-note

kubeadm: Aggregate the token functionality in sane packages.
- Factor out token constants to kubeadmconstants.
 - Move cmd/kubeadm/app/util/{,token/}tokens.go
 - Use the token-id, token-secret, etc constants provided by the bootstrapapi package
 - Move cmd/kubeadm/app/master/tokens.go to cmd/kubeadm/app/phases/token/csv.go

This refactor basically makes it possible to hook up kubeadm to the BootstrapSigner controller later on
