**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.

add kubectl create --raw -f
Adds `--raw` to `kubectl create` to match `kubectl get --raw`. It re-uses the transport, reads the input stream (stdin or a single file for now) and posts directly to the endpoint specified. This let's you direct data directly at a subresource (as a for instance). I'd like to see this extended to `kubectl replace` too, so that we have full access to subresources via scripting without having to reproduce the transports.

Polymorphic Scale Client
This PR introduces a polymorphic scale client based on discovery information that's able to scale scalable resources in arbitrary group-versions, as long as they present the scale subresource in their discovery information.
Currently, it supports `extensions/v1beta1.Scale` and `autoscaling/v1.Scale`, but supporting other versions of scale if/when we produce them should be fairly trivial.
It also updates the HPA to use this client, meaning the HPA will now work on any scalable resource, not just things in the `extensions/v1beta1` API group.
**Release note**:
```release-note
Introduces a polymorphic scale client, allowing HorizontalPodAutoscalers to properly function on scalable resources in any API group.

kubectl resource builder to use versioned list
Switch to using a versioned listed when return an object from the resource builder.
This is necessary to allow cli's built outside the kubernetes/kubernetes repo to vendor the resource builder logic without vendoring all of Kubernetes.
The following commands call the modified function. (identified by changing the function name and recompiling)
- [x] `attach`
- pkg/kubectl/cmd/attach.go:155: builder.Do().Object
- passes to `AttachablePodForObject` which does not support Lists of any kind
- [x] `get`
- pkg/kubectl/cmd/get.go:251: r.Object
- [x] check if isList with `IsListType` -> `GetItemsPtr` -> check for presence of `Items` field
- [x] pass to `ResourceVersion` -> `CommonAccessor` -> checks for `metav1.ListInterface` (which this PR introduces a compile time check to ensure v1.List implements this)
- [x] pass to `ExtractList` -> checks if items implement `runtime.RawExtension`
- [x] `rolling_update`
- pkg/kubectl/cmd/rollingupdate.go:207: request.Object
- only accepts lists of length 1. updated in PR to support both api.List and v1.List
- [x] `rollout_status`
