Switch RBAC subject apiVersion to apiGroup in v1beta1
Referencing a subject from an RBAC role binding, the API group and kind of the subject is needed to fully-qualify the reference.
The version is not, and adds complexity around re-writing the reference when returning the binding from different versions of the API, and when reconciling subjects.
This PR:
* v1beta1: change the subject `apiVersion` field to `apiGroup` (to match roleRef)
* v1alpha1: convert apiVersion to apiGroup for backwards compatibility
* all versions: add defaulting for the three allowed subject kinds
* all versions: add validation to the field so we can count on the data in etcd being good until we decide to relax the apiGroup restriction
```release-note
RBAC `v1beta1` RoleBinding/ClusterRoleBinding subjects changed `apiVersion` to `apiGroup` to fully-qualify a subject. ServiceAccount subjects default to an apiGroup of `""`, User and Group subjects default to an apiGroup of `"rbac.authorization.k8s.io"`.

Promote TokenReview to v1
Peer to https://github.com/kubernetes/kubernetes/pull/40709
We have multiple features that depend on this API:
- [webhook authentication](https://kubernetes.io/docs/admin/authentication/#webhook-token-authentication)
- [kubelet delegated authentication](https://kubernetes.io/docs/admin/kubelet-authentication-authorization/#kubelet-authentication)
- add-on API server delegated authentication
The API has been in use since 1.3 in beta status (v1beta1) with negligible changes:
- Added a status field for reporting errors evaluating the token
This PR promotes the existing v1beta1 API to v1 with no changes
Because the API does not persist data (it is a query/response-style API), there are no data migration concerns.
This positions us to promote the features that depend on this API to stable in 1.7

update binding details to design/persistent-storage doc
Scroll down to "Matching and binding" (there is no TOC).
An issue I see is that this level of detail may get stale quickly and there is no built-in mechanism to update this doc when the binding code changes. However, several people on my team, from time to time, want to know greater details about binding rules, eg. for test writing, updating/creating other docs, etc.
PTAL @jsafrane @pmorie @copejon
If it's decided this type of content (high level overview of an algorithm/implementation) is useful, but docs/design/ is not the right location, perhaps a new dir can be created for this type of content?

kubectl: add less verbose version
The kubectl version output is very complex and makes it hard for users
and vendors to give actionable information. For example during the
recent Kubernetes 1.4.3 TLS security scramble I had to write a one-liner
for users to get out the version number to give to figure out if they
are vulnerable:
```
$ kubectl version | grep -i Server | sed -n 's%.*GitVersion:"\([^"]*\).*%\1%p'
```
Instead this patch outputs simply output by default
```
./kubectl version
Client Version: v1.4.3
Server Version: v1.4.3
```
Adding the `--verbose` flag will output the old format.

Use generation in pod disruption budget
Fixes#35324
Previously it was possible to use allowedDirsruptions calculated for the previous spec with the current spec. With generation check API servers always make sure that allowedDisruptions were calculated for the current spec.
At the same time I set the registry policy to only accept updates if the version based on which the update was made matches to the current version in etcd. That ensures that parallel eviction executions don't use the same allowed disruption.

Switch DisruptionBudget api from bool to int allowed disruptions [only v1beta1]
Continuation of #34546. Apparently it there is some bug that prevents us from having 2 different incompatibile version of API in integration tests. So in this PR v1alpha1 is removed until testing infrastructure is fixed.
Base PR comment:
Currently there is a single bool in disruption budget api that denotes whether 1 pod can be deleted or not. Every time a pod is deleted the apiserver filps the bool to false and the disruptionbudget controller sets it to true if more deletions are allowed. This works but it is far from optimal when the user wants to delete multiple pods (for example, by decreasing replicaset size from 10000 to 8000).
This PR adds a new api version v1beta1 and changes bool to int which contains a number of pods that can be deleted at once.

Improvements to CLI usability and maintainability
Improves `kubectl` from an usability perspective by
1. Fixing how we handle terminal width in help. Some sections like the flags use the entire available width, while others like long descriptions breaks lines but don't follow a well established max width (screenshot below). This PR adds a new responsive writer that will adjust to terminal width and set 80, 100, or 120 columns as the max width, but not more than that given POSIX best practices and recommendations for better readability.
2. Adds our own normalizers for long descriptions and cmd examples which allows us better control about how things like lists, paragraphs, line breaks, etc are printed. Features markdown support. Looks like `templates.LongDesc` and `templates.Examples` instead of `dedent.Dedend`.
3. Allows simple reordering and reuse of help and usage sections.
3. Adds `verify-cli-conventions.sh` which intends to run tests to make sure cmd developers are using what we propose as [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md). Just a couple simple tests for now but the framework is there and it's easy to extend.
4. Update [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md) to use our own normalizers instead of `dedent.Dedent`.
