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.

Rename Detach() parameter.
`Detach()` does not get device name, it gets volume name. Parameters named `deviceMountPath` or `deviceName` just confuses developers.
Note that this PR just renames parameters here and there, there should be no behavior change.

kubelet: dockershim: remove orphaned checkpoint files
Fixes https://github.com/kubernetes/kubernetes/issues/55070
Currently, `ListPodSandbox()` returns a combined list of sandboxes populated from both the runtime and the dockershim checkpoint files. However the sandboxes in the checkpoint files might not exist anymore.
The kubelet sees the sandbox returned by `ListPodSandbox()` and determines it shouldn't be running and calls `StopPodSandbox()` on it. This generates an error when `StopContainer()` is called as the container does not exist. However the checkpoint file is not cleaned up. This leads to subsequent calls to `StopPodSandbox()` that fail in the same way each time.
This PR removes the checkpoint file if StopContainer fails due to container not found.
The only other place `RemoveCheckpoint()` is called, except if it is corrupt, is from `RemoveSandbox()`. If the container does not exist, what `RemoveSandbox()` would have done has been effectively been done already. So this is just clean up.

output empty creationTimestamp as null
**Release note**
```release-note
NONE
```
Updates the value of the `creationTimestamp` field to be `null`
when empty, to keep parity between it and `deletionTimestamp`.
Adds a round-trip test to ensure that unstructured objects containing
empty metadata fields are able to be re-converted back into internal
or external objects. Prior to the proposed patch in this PR, an
unstructured object whose `.metadata.creationTimestamp` value had
been set through the metadata accessor to an empty value
(`metav1.Time{}` in this case), was unable to be re-converted to an
internal or external type using the runtime decoder. Conversion would
fail with the error:
```
unstructured_test.go:177: FromUnstructured failed: parsing time "" as "2006-01-02T15:04:05Z07:00": cannot parse "" as "2006"

kube-proxy IPVS: Fix IPVS availability check
**What this PR does / why we need it**:
The current implementation of `CanUseIPVSProxier()` reads `/proc/modules`
to check whether IPVS related kernel modules can be loaded.
You might get a false-negative when the kernel modules are installed to
the system but haven't been loaded into the kernel.
This patch firstly try to run `modprobe` to load specified kernel
modules, then just log warnings if error occured.
Secondly, it will check loaded kernel modules by reading
`/proc/modules`, return an error if any required module is missing.
This change will not break the compatability of existing implementation.
Running kube-proxy in a container without mounting `/lib/modules` will
cause `modprobe` warnings, but not raise an error if all required modules are
present in the host kernel.

**Release note**:
