Check for available volume before attach/delete in EBS
We should check for available volume before performing
attach or delete of EBS volume.
Mutable API calls such as Attach Volume or Delete Volume has much lower quota than immutable API calls such as DescribeVolume or DescribeInstance. Checking for available state before attach or delete
ensures that we are not making useless API calls.

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.

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.

+++++++++++++++++++++++++++++++++
* Windows CNI Support
(1) Support to use --network-plugin=cni
(2) Handled platform requirement of calling CNI ADD for all the containers.
(2.1) For POD Infra container, netNs has to be empty
(2.2) For all other containers, sharing the network namespace of POD container,
should pass netNS name as "container:<Pod Infra Container Id>", same as the
NetworkMode of the current container
(2.3) The Windows CNI plugin has to handle this to call into Platform.
Sample Windows CNI Plugin code to be shared soon.
* Sandbox support for Windows
(1) Sandbox support for Windows. Works only with Docker runtime.
(2) Retained CONTAINER_NETWORK as a backward compatibilty flag,
to not break existing deployments using it.
(3) Works only with CNI plugin enabled.
(*) Changes to reinvoke CNI ADD for every new container created. This is hooked up with PodStatus,
but would be ideal to move it outside of this, once we have CNI GET support

kubenet: yield lock while executing CNI plugin.
The CNI plugin can take up to 3 seconds to execute. CNI plugins can safely be
executed in parallel, so yield the lock to speed up pod creation.
This caused problems with the pod latency tests - previously, CNI plugins executed
in under 20ms. Now they must wait for DAD to finish and addresses to leave
tentative state.
Fixes: #54651
**What this PR does / why we need it**:
After upgrading CNI plugins to v0.6 in #51250, the pod latency tests began failing. This is because the plugins, in order to support IPv6, need to wait for DAD to finish. Because this
delay is while the kubenet lock is held, it significantly slows down the pod creation rate.
**Special notes for your reviewer**:
The CNI plugins also do locking for their critical paths, so it is safe to run them concurrently.
**Release note**:
```release-note
NONE
```
