kubeadm: Demote --self-hosted to master config file.
**What this PR does / why we need it**:
kubeadm init --self-hosted was meant to be a short lived hack to enable self-hosted deployments until we're ready to make them the default. Rather than shipping this in 1.6 (for the first time) we will move this to the config file as it is presently only an advanced feature, leaving us with more well supported ways to remove it in the future.

add sample fuzzing tests
Make fuzzing tests as simple as possible from both the API installer and the scheme, so its easy to add for api groups and so that I can build a scheme and then make sure I got it right.

Some imports dont exist yet (or so it seems) in client-go (examples
being:
- "k8s.io/kubernetes/pkg/api/validation"
- "k8s.io/kubernetes/pkg/util/initsystem"
- "k8s.io/kubernetes/pkg/util/node"
one change in kubelet to import to client-go
Recent changes to support multiple methods for discovery meant that
"kubeadm init" no longer was sufficient and users would need to add
"--discovery token://" to achieve the same results.
Instead lets assume discovery if the user does not specify anything else
to maintain parity and the brevity of our original instructions.

Remove json serialization annotations from internal types
fixes#3933
Internal types should never be serialized, and including json serialization tags on them makes it possible to accidentally do that without realizing it.
fixes in this PR:
* types
* [x] remove json tags from internal types
* [x] fix references from serialized types to internal ObjectMeta
* generation
* [x] remove generated json codecs for internal types (they should never be used)
* kubectl
* [x] fix `apply` to operate on versioned object
* [x] fix sorting by field to operate on versioned object
* [x] fix `--record` to build annotation patch using versioned object
* hpa
* [x] fix unmarshaling to internal CustomMetricTargetList in validation
* thirdpartyresources
* [x] fix encoding API responses using internal ObjectMeta
* tests
* [x] fix tests to use versioned objects when checking encoded content
* [x] fix tests passing internal objects to generic printers
follow ups (will open tracking issues or additional PRs):
- [ ] remove json tags from internal kubeconfig types (`kubectl config set` pathfinding needs to work against external type)
- [ ] HPA should version CustomMetricTargetList serialization in annotations
- [ ] revisit how TPR resthandlers encoding objects
- [ ] audit and add tests for printer use (human-readable printer requires internal versions, generic printers require external versions)
- [ ] add static analysis tests preventing new internal types from adding tags
- [ ] add static analysis tests requiring json tags on external types (and enforcing lower-case first letter)
- [ ] add more tests for `kubectl get` exercising known and unknown types with all output options

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")

kubeadm: Implement support for symbolic labels in --use-kubernetes-version
**What this PR does / why we need it**: This patch adds "stable", "latest" and other labels as valid versions in "kubeadm init --use-kubernetes-version" flag.
Now, defaults can be pointing to "stable" and users will always get
latest available stable build of Kubernetes via kubeadm.
There is no need anymore to hardcode version string inside kubeadm
binary.
It is also possible to use labels like "latest" or point to exact
branch: "stable-1.4"
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
**Release note**:
```release-note
- kubeadm init --use-kubernetes-version now understands "stable","latest", "stable-1.4" and other labels as valid version. It will fetch actual build number from release servers.
```

support customize repository prefix of image through environment KUBE…
## Problem
kubeadm does not support customize repository prefix of image. this prevent us from using our own image repository to deploy k8s.
## Fix
make ```gcr.io/google_containers/ ``` be configurable.
ADD environment variable KUBE_REPO_PREFIX
