While moving device_plugin_handler_test.go from pkg/kubelet/cm/ to
pkg/kubelet/cm/deviceplugin/, we can no longer uses cm in its tests
because that would cause a cycle dependency. To solve this problem,
I moved the main cm GetResources functionality as well as part of the
current device plugin handler Allocate functionality into a new device
plugin handler function, GetDeviceRunContainerOptions(). This
refactoring is also needed by another PR 51895 that moves device
allocation into admission phase. Now device plugin handler Allocate()
first checks whether there is cached device runtime state and only
issues Allocate grpc call if there is no cached state available.
The new GetDeviceRunContainerOptions() function simply returns device
runtime config from the cached state. To support this change, extended the
podDevices struct and checkpoint data structure with device runtime state.

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.

Need to validate taint effect when removing taints.
Instead of reporting taint not found, it's better to report user
that the effect is invalid. This will help user to check errors.
So when user tries to remove a taint, two conditions will be checked:
1. Whether or not the effect is an empty string.
2. Whether or not the non-empty effect is a valid taint effect.

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`
- pkg/kubectl/cmd/rollout/rollout_status.go:107: r.Object
- passes to `ResourceVersion` -> `CommonAccessor` -> checks for `metav1.ListInterface`

**Special notes for your reviewer**:
Currently, it seems that func `IsResourceNameValid` is not used outside and could be changed to internal.
But as Renaud commented, it is designed for potential usage from users outside.
And I could not find a better position to place the func, except for file `utils.go`. So, shall we just retain the `utils.go` file, and maybe for possible expansion in the future?

Use GetByKey() in typeLister_NonNamespacedGet
The Get() function of non-namespace lister passes a temporary object to
indexer.Get() in order to fetch the actual object from the indexer. This
may cause Go to allocate the temporary object on the heap instead of the
stack, as it is passed into interfaces. For non-namespaced objects,
Get(&Type{ObjectMeta: v1.ObjectMeta{Name: name}}) should be equivalent
to GetByKey(name).
This could be the root cause of excessive allocations, e.g. in tests
clusterRoleLister.Get() has trigger 4 billion allocations. See
openshift/origin#16954

Make AllocateResponse artifacts global across all devices per container in device plugin API
The current version of Device plugins returns artifacts (env vars, mounts, devices) per device, per container. This is not necessary and results in complex merging issues on kubelet side
There can still be a conflict if the artifacts returned by device plugin conflicts with the pod spec. In that case, I'd recommend failing pods in kubelet. This is yet to be addressed.
The go package name for device plugin apis is updated from `pkg/kubelet/apis/deviceplugin/v1alpha1` to `pkg/kubelet/apis/deviceplugin/v1alpha` (sub-version dropped) because we expect the alpha version to change until it graduates to beta and changing the go package everytime the actual alpha version changes is too tedious.
```release-note
Device plugin Alpha API no longer supports returning artifacts per device as part of AllocateResponse.
```
TODO:
- [x] Bump kubelet side API version
- [X] Post an updated device plugin image that works with the new API version
- [ ] Stabilize e2es (This PR needs to be merged since there is a dependency on the plugin side for vendoring)

Fixed the lease endpoint reconciler creation of kubernetes endpoint and lease file ttl. #53803
Fixed the prefix used to create the kubernetes endpoint and the ttl value used for lease files.
Fixes: #53803
There is no use case known for passing artifacts per device as it currently exists. The current API is also
complex to use for simple clients. Hence this PR creates a flat namespace where artifacts like environment variables
and mount points apply globally to all devices returned as part of AllocateResponse proto.

This updates the HPA controller to use the polymorphic scale client from
client-go. This should enable HPAs to work with arbitrary scalable
resources, instead of just those in the extensions API group (meaning we
can deprecate the copy of ReplicationController in extensions/v1beta1).
It also means that the HPA controller now pays attention to the
APIVersion field in `scaleTargetRef` (more specifically, the group part
of it).
Note that currently, discovery information on which resources are
available where is only fetched once (the first time that it's
requested). In the future, we may want a refreshing discovery REST
mapper.
