Fixes kubectl Pod Disruption Budget and adds tests
**What this PR does / why we need it**:
This PR fixes several kubectl Pod Disruption Budget issues:
* The `min-available` parameter in Pod Disruption Budget V1 is not required (otherwise it will never use the default value)
* Removes the deprecated `min-available` default in Pod Disruption Budget V2
* The `selector` parameter in Pod Disruption Budget V2 is required
* Fixes (typo) the `max-unavailable` parameter check in Pod Disruption Budget V2
* Fixes some assertion error messages where the value printed was always the zero value of the parameter type instead of the parameter provided
* Updated kubectl Pod Disruption Budget to use policy V1Beta1 instead of unversioned API (see https://github.com/kubernetes/kubectl/issues/90)
* Add missing tests

If a user edits last-applied-configuration and it doesn't have an
apiVersion or kind, the command should error out. Now that we check for
kind and version on the unstructured object typer, the previously
passing test now correctly fails. Add a new explicit failure test and
make the existing test pass.

Change the name of the flag to something slightly more user-friendly,
while making it default true. The flag is kept so that someone can
revert it temporarly if things go wrong.
Add a new EmptyResource class that implements openapi.Resources, but
just doesn't have any resources. That is useful for tests that expect
the OpenAPISchema to be working, but don't expect any actual result.
Also implement CreateOpenAPISchemaFunc to simply plug in the TestFactory
code when you want to use an actual APISchema.

Enhance label and taint documentation in kubectl
**What this PR does / why we need it**:
This adds some language around how taint and label keys can have a domain + '/' in front of them. From the current documentation, it would seem like these are not allowed even though [well known labels](https://kubernetes.io/docs/reference/labels-annotations-taints/) have them.
Also, it seemed unclear (to me) that both the label's key and value can be 63 characters long. I wanted to clarify this.

kubectl explain ingress.spec.rules.http.paths. is valid
and defaults to kubectl explain ingress.spec.rules.http.paths
Rational: We use kubectl explain by adding fields
(e.g. service, then service.spec, then service.spec.ports ...)
so it's very easy to forget a trailing . at the end. We should
ignore the trailing period and display the result without it.

Fix an unreachable kubectl explain field lookup test
In error case, the condition `gotErr != test.err && gotPath !=
test.expectedPath` never fulfill because in this case both gotPath and
test.expectedPath are always an empty string. So the err “err: `field "what?"
does not exist`” doesn’t get tasted. For example, if you change the value of
`err:` to anything, the test still will pass. Also, since gotPath is empty
string in case of err, in the output error we probably don’t want to display
path.

This change makes ReconcileOptions fully reusable by:

3. All fields are now checked by Validate as a way to document that they should be set before calling RunReconcile.

Workloads V1
**What this PR does / why we need it**: This PR promotes the Deployment, ReplicaSet, and DaemonSet StatefulSet, ControllerRevision kinds to the apps/v1 group version.
https://github.com/kubernetes/features/issues/353
**Special notes for your reviewer**:
There will be at least two followups to this PR. The first to add a scale sub-resource when the correct location is resolved, and the second to deal with Conditions in the workloads API.
While it would have been preferable to move the kinds individually providing a lesser burden on reviewers, this proved impracticable due to the intricacies of version resolution in kubectl for objects of the different kinds in the same group.
```release-note
DaemonSet, Deployment, ReplicaSet, and StatefulSet have been promoted to GA and are available in the apps/v1 group version.

The encoding and decoding here uses only `k8s.io/apimachinery/pkg/apis/meta/v1.APIGroupList` and `k8s.io/apimachinery/pkg/apis/meta/v1.APIResourceList` which are not internal version. So it should be safe.

Add an import-boss file to inventory what kubectl depends on, so
we can prune this list over time and eventually get kubectl out
of the main k/k repository.
To update this list, You can list the dependencies using:
go list -f '{{ join .Deps "\n"}}' k8s.io/kubernetes/cmd/kubectl | grep
k8s.io/kubernetes | grep -v kubectl | grep -v vendor
Add the generated list of package names to .import-restrictions
file. Then run the hack/verify-import-boss.sh until you have you have
all the packages needed.

Added missing tests which checks proper handling of `%s` in arguments for command `kubectl apply view-last-applied`
**Which issue this PR fixes**
#54645
**Special notes for your reviewer**:
Added a test case to cover specific issue described.
It fails on version `v1.7.3`..`v1.7.9` and passes since `v1.8.0`.
P.S. Not sure if there is already a lower level test which covers this case in the k8s test suite. I would recommend to add this test, so the issue would not reoccur.

Create kubectl's own instance of Scheme and Registry
Create kubectl's own instance of Registry and Scheme.
Switch most command that doesn't depend on internal types to use kubectl's own scheme and register.
There are some hack of registering the internal types in some of unit test now, they should be gone after switch to the external type.
Switch kubectl's factory code to use kubectl's scheme will create a lot of ripples.
I don't want make this PR a super giant PR, so I will do it in a followup PR.
Partially addressed #48564.
Copy the summary from https://github.com/kubernetes/kubernetes/pull/54533#issuecomment-340522302:
- creates pkg/kubectl/scheme (install.go and scheme.go) with
deps on properly vendored k8s.io packages.
- deletes about 80% percent of dependence on pkg/api/legacyscheme
- replaces direct dependence from pkg/kubectl on
pkg/apis/rbac
to a vendor style dependence on
k8s.io/api/rbac
and removes dependencies on rbac paths containing internalversion
- replaces almost 50% of direct dependence on pkg/api with (properly vendored)
k8s.io/api/core/v1
- deletes all of dependence on pkg/apis/policy and k8s.io/api/policy/v1beta1

Support api chunking in kubectl get
This enables chunking in the resource builder to make it easy to
retrieve resources in pages and visit partial result sets. This adds
`--chunk-size` to `kubectl get` only so that users can get comfortable
with the use of chunking in beta. Future changes will enable chunking
for all CLI commands so that bulk actions can be performed more
efficiently.
```
$ kubectl get pods --all-namespaces
... print batch of 500 pods ...
... print second batch of 500 pods ...
...
```
@kubernetes/sig-cli-pr-reviews @kubernetes/sig-api-machinery-pr-reviews
```release-note
`kubectl get` will by default fetch large lists of resources in chunks of up to 500 items rather than requesting all resources up front from the server. This reduces the perceived latency of managing large clusters since the server returns the first set of results to the client much more quickly. A new flag `--chunk-size=SIZE` may be used to alter the number of items or disable this feature when `0` is passed. This is a beta feature.

Remove federation
This PR removes the federation codebase and associated tooling from the tree.
The first commit just removes the `federation` path and should be uncontroversial. The second commit removes references and associated tooling and suggests careful review.
Requirements for merge:
- [x] Bazel jobs no longer hard-code federation as a target ([test infra #4983](https://github.com/kubernetes/test-infra/pull/4983))
- [x] `federation-e2e` jobs are not run by default for k/k
**Release note**:
```release-note
Development of Kubernetes Federation has moved to github.com/kubernetes/federation. This move out of tree also means that Federation will begin releasing separately from Kubernetes. The impact of this is Federation-specific behavior will no longer be included in kubectl, kubefed will no longer be released as part of Kubernetes, and the Federation servers will no longer be included in the hyperkube binary and image.
