kubeadm: must lower-case token portion used in DNS label.
**What this PR does / why we need it**: In Kubernetes, DNS labels must be lower-case. `kubeadm` doesn't care when creating certain objects through the API. This PR fixes that erroneous behavior.
**Which issue this PR fixes**: fixes https://github.com/kubernetes/kubeadm/issues/104

kubeadm: refactored token discovery.
**What this PR does / why we need it**: refactored `kubeadm` token discovery to follow the discovery interface and use new TLS bootstrap mechanism.
/cc @luxas @mikedanese
Adds kubeadm subcommands to create, list, and delete bootstrap tokens.
Tokens can be created with a TTL duration, or 0 for tokens that will not
expire. The create command can also be used to specify your own token
(for use when bootstrapping masters and nodes in parallel), or update an
existing token's secret or ttl.
Marked "ex" for experimental for now as the boostrap controllers are not
yet hooked up in core.

kubeadm UX improvements for the v1.5 stable release
This PR targets the next stable kubeadm release.
It's work in progress, but please comment on it and review, since there are many changes.
I tried to group the commits logically, so you can review them separately.
Q: Why this large PR? Why not many small?
A: Because of the Submit Queue and the time it takes.
PTAL @kubernetes/sig-cluster-lifecycle
_Edit:_ This work was splitted up in three PRs in total
Fix boilerplates, comments in the code and make the output of kubeadm more user-friendly
Start using HostPKIPath and KubernetesDir everywhere in the code, so they can be changed for real
More robust kubeadm reset code now.
Removed old glog-things from app.Run()
Renamed /etc/kubernetes/cloud-config.json to /etc/kubernetes/cloud-config since it shouldn't be a json file
Simplification of the code
Less verbose output from master/pki.go
Cleaned up dead code
Start a small logging/output framework:
- fmt.Println("[the-stage-here] Capital first letter of this message. Tell the user what the current state is")
- fmt.Printf("[the-stage-here] Capital first letter. Maybe a [%v] in the end if an error should be displayed. Always ends with \n")
- fmt.Errorf("Never starts with []. Includes a short error message plus the underlying error in [%v]. Never ends with \n")

Add a cloudprovider validator flag to kubeadm and update the DNS spec
Broken out from: https://github.com/kubernetes/kubernetes/pull/37568
This PR creates a flag for `cloud-provider` that validates the value before `RunInit()` is run, which makes it now act as a "real" flag
Then it removes the `k8s.io/kubernetes/pkg/cloudprovider` dependency, which makes the binary ~40MB smaller! That's _really_ worth it!
In the second commit, the DNS addon is updated to the latest version: https://github.com/kubernetes/kubernetes/blob/master/cluster/addons/dns/skydns-rc.yaml.base

Revert "[kubeadm] use iteration instead of recursion in function"
Reverts kubernetes/kubernetes#36625
Removing the recursive call means that `n` is never updated, so you never succeed in the update, and you've creating an infinite loop.
Also, this entire bit of functionality should be a patch and you won't have to worry about conflicts.
