move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.
@kubernetes/sig-api-machinery-misc @kubernetes/api-reviewers @kubernetes/api-approvers
@derekwaynecarr since most of these are related to the kubelet

Add support for creating resources that are not immediately visible to
naive clients, but must first be initialized by one or more privileged
cluster agents. These controllers can mark the object as initialized,
allowing others to see them.
Permission to override initialization defaults or modify an initializing
object is limited per resource to a virtual subresource "RESOURCE/initialize"
via RBAC.
Initialization is currently alpha.
As part of https://github.com/kubernetes/community/pull/132, thsi commit
adds a generic webhook admission controller. This plugin allows for a
completely declarative approach for filtering/matching admission requests
and for matching admission requests, calls out to an external webhook for
handling admission requests.

ResourceQuota admission control injects registry
**What this PR does / why we need it**:
The `ResourceQuota` admission controller works with a registry that maps a GroupKind to an Evaluator. The registry used in the existing plug-in is not injectable, which makes usage of the ResourceQuota plug-in in other API server contexts difficult. This PR updates the code to support late injection of the registry via a plug-in initializer.

Change all the existing admission init blocks to call a Register function
**What this PR does / why we need it**:
this is a two stage refactor when done there will be no init block in admission plugins.
Instead all plugins expose Register function which accept admission.Plugins instance.
The registration to global plugin registry happens inside Register function

Tighten validation of mirror pod annotations
Tightens validation for pods with a mirror pod annotation:
1. spec.nodeName must be set
2. makes the mirror pod annotation immutable
3. starts validating pod-specific annotations during pod status update
None of these changes affect usage of the mirror pod annotation by kubelets, which only set it on pod creation (verified this is true back to 1.5.x)
the second commit updates the pod validation tests to look for specific error messages (best reviewed ignoring whitespace changes)
This is the validation portion of https://github.com/kubernetes/community/blob/master/contributors/design-proposals/kubelet-authorizer.md and https://github.com/kubernetes/features/issues/279
```release-note
Mirror pods must now indicate the nodeName they are bound to on creation. The mirror pod annotation is now treated as immutable and cannot be added to an existing pod, removed from a pod, or modified.

Prepare for move zz_generated_deepcopy.go to k8s.io/api
This is in preparation to move deep copies to with the types to the types repo (see https://github.com/kubernetes/gengo/pull/47#issuecomment-296855818). The init() function is referring the `SchemeBuilder` defined in the register.go in the same packge, so we need to revert the dependency.
This PR depends on https://github.com/kubernetes/gengo/pull/49, otherwise verification will fail.

Extend the gc admission plugin to check ownerReference.blockOwnerDeletion
#Extend the gc admission plugin to prevent user who doesn't have delete permission of the *owner* from changing blockOwnerDeletion field of existing ownerReferences, or adding ownerReference with blockOwnerDeletion=true.
The plugin need a RESTMapper to translate ownerRef.Kind to Resource. It should be using a dynamic one. However, as discussed in https://github.com/kubernetes/kubernetes/pull/42615, such a RESTMapper will be built after watchable discovery API is implemented, so in this PR the plugin is using the `api.Registry.RESTMapper()`, which is also [used](https://github.com/kubernetes/kubernetes/blob/master/cmd/kube-controller-manager/app/core.go#L165-L166) by the garbage collector currently.
```release-note
Extending the gc admission plugin so that a user who doesn't have delete permission of the *owner* cannot modify blockOwnerDeletion field of existing ownerReferences, or add new ownerReference with blockOwnerDeletion=true

remove defaulting from conversion path
follow up for #42764
* remove call to defaulting from conversion path (defaulting is a separate step from conversion)
* remove non-top-level-object defaulting registration (unused after conversion call is removed)
* generate missing top-level defaults for some api groups:
* autoscaling/v2alpha1
* policy/v1alpha1
* policy/v1beta1
* register top-level defaults for some api groups that were missing them:
* autoscaling/v2alpha1
* settings/v1alpha1

Non global admission plugin registry
For testing the global state is a problem. This PR turns the actual registry into a struct that must be instantiated. For the beginning, we do this in `pkg/kubeapiserver/admission`. In some follow-up (where we hunt down all globals some day), we will move this into the genericapiserver.

Conversionlint
**What this PR does / why we need it**:
This PR adds a comment placeholder for the exported or public functions in conversion generator files. Such functions without a comment results into golint failure in various generated files. The changes in this patch takes care of about 36 related lint failures.
Given below is an example lint error,
zz_generated.conversion.go:91:1: exported function Convert_v1alpha1_Binding_To_servicecatalog_Binding should have comment or be unexported
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
Considering minor changes no issue is created.
**Special notes for your reviewer**:
Hello, I am trying to fix golint failures as we see them in the kubernetes-incubator/service-catalog project. I have separate PRs opened for lint issues related to other generator code which are in separate libraries like gengo. Thanks!
