Add PriorityClass API object under new "scheduling" API group
**What this PR does / why we need it**: This PR is a part of a series of PRs to add pod priority to Kubernetes. This PR adds a new API group called "scheduling" with a new API object called "PriorityClass". PriorityClass maps the string value of priority to its integer value.
**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**: Given the size of this PR, I will add the admission controller for the PriorityClass in a separate PR.
**Release note**:

api types: fix protobuf names that are different from JSON name
This PR fixes the naming of protobuf fields that are mismatched when compared to the JSON names. Because protobuf names aren't actually used during serialization, just the index, I think we can update these safely without changing the over the wire encoding (note that generated.pb.go doesn't change).
Can someone verify that fixing the name won't impact backward compatibility?

*: remove --insecure-allow-any-token option
~Since the authenticator is still used in e2e tests, don't remove
the actual package. Maybe a follow up?~
edit: e2e and integration tests have been switched over to the tokenfile
authenticator instead.
```release-note
The --insecure-allow-any-token flag has been removed from kube-apiserver. Users of the flag should use impersonation headers instead for debugging.

fix NamespaceLifecycle admission
forceLiveLookupCache is designed to save recently deleted namespaces.
But currently, cluster scoped resources are also put into it.
For example, when we run:
kubectl delete clusterrole edit
The "edit" is put into forceLiveLookupCache as a deleted namespace.
This change fix the invalid action.

This is the final commit, which is based on top of PR 46044 and 46138, and provides
support for Ipv6 for the ChooseHostInterface() and ChooseBindAddress() functions.
The commit includes the following...
- Parses default routes from /proc/net/ipv6_route file.
- Collected IPv6 routes are added to the Ipv4 routes collected.
- ChooseHostInteface semantics remain the same:
* If no Ipv4 route file, the system interfaces will be checked for a global IP.
* Otherwise, default routes will be used to find a global IP.
* If there is a failure getting IP from default routes, an error is reported.
* Although IPv6 routes are also used, IPv4 routes have precedence.
- Any failure getting IPv6 routes is ignored, and will proceed with IPv4 routes.
- Scans all IPv4 routes looking for interfaces with global IP, before looking at
IPv6 routes.
- Increased code coverage to 90.2%, covering all new and modified code (except for
the top level API functions, which would need to be checked with integration/e2e
tests.
This would complete IPv6 support in this area of the code.
Updated to rebased for changes from 46138/46044, and based on review comments.

Static deepcopy – phase 1
This PR is the follow-up of https://github.com/kubernetes/kubernetes/pull/36412, replacing the
dynamic reflection based deepcopy with static DeepCopy+DeepCopyInto methods on API types.
This PR **does not yet** include the code dropping the cloner from the scheme and all the
porting of the calls to scheme.Copy. This will be part of a follow-up "Phase 2" PR.
A couple of the commits will go in first:
- [x] audit: fix deepcopy registration https://github.com/kubernetes/kubernetes/pull/48599
- [x] apimachinery+apiserver: separate test types in their own packages #48601
- [x] client-go: remove TPR example #48604
- [x] apimachinery: remove unneeded GetObjectKind() impls #48608
- [x] sanity check against origin, that OpenShift's types are fine for static deepcopy https://github.com/deads2k/origin/pull/34
TODO **after** review here:
- [x] merge https://github.com/kubernetes/gengo/pull/32 and update vendoring commit

adding validations on kube-apiserver audit log options
**What this PR does / why we need it**:
The kube-apiserver does not check the validity of the following audit log options `--audit-log-maxage`, `--audit-log-maxage`, `--audit-log-maxage`. If these options are set to negative numbers, the kube-apiserver will not detect these invalid settings. This PR adds validations on these audit log options.

Update two dependencies
**What this PR does / why we need it**:
github.com/stretchr/testify - main desired update. Old version has bugs. Specifically I encountered https://github.com/stretchr/testify/issues/347 which was fixed a year ago.
github.com/davecgh/go-spew/spew is set to the newest version, a bit
newer than required by testify. Updated from version 6 Nov 2015 to
27 Jun 2017.
github.com/stretchr/objx is not updated - testify uses version
from 27 May 2014 which is older than 28 Sep 2015 used now (latest
actually). In practice there is only a tiny difference - one method was
removed in new version.

Never prevent deletion of resources as part of namespace lifecycle
Namespace lifecycle should not prevent deletion of resources... its purpose is to prevent creation of resources in a terminating namespace, or create/update of resources in a non-existent namespace.

Remove old, core/v1 specific constructs from RESTClient
Now that metav1 is abstracted from the APIs, RESTClient should also be agnostic to the core API.
* Remove `LabelSelectorParam` and `FieldSelectorParam` - use `VersionedParams` with `ListOptions`
* Remove `UintParam`
* Remove all legacy field selector logic from `VersionedParams` - ParameterCodec now handles that
* Remove special parameters (like `timeout`) which is no longer set by most clients
