code-gen: add +groupGoName to allow unique Go identifiers in clientsets and informers

We use the first segement of the GroupName as Go name. Hence, a GroupName
"policy.k8s.io" and "policy.authorization.k8s.io" could not live in the
same clientset or shared informer factory. This PR add another tag:

```

apiextensions/examples: add typed client

It was discussed in https://github.com/kubernetes/kubernetes/pull/52753#issuecomment-337840762 to add a typed client example to apiextensions-apiserver and remove the controller part.

For an example controller, we have [`k8s.io/sample-controller`](https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/sample-controller) now.

Fix scheduler predicates test that may violate DNS label rules

**What this PR does / why we need it**:

This commit fixes an issue where in clusters which have FQDN as the node names,
one of the scheduling predicates tests will fail because it will try and run a

could look like "filler-pod-kube-node-0.kubelet.mesos".

kubeadm: reset: use crictl to reset containers

@luxas PTAL
Signed-off-by: Antonio Murdaca <runcom@redhat.com>



**What this PR does / why we need it**:

This patch makes kubeadm to try and reset containers using `crictl` first instead of docker. The reason is that kubeadm reset is ineffective with new container runtimes using the CRI (like CRI-O).
This patch uses `crictl` first and falls back to `docker` in case `crictl` isn't available.

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.

Fixes https://github.com/kubernetes/kubernetes/issues/55014

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.

`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"
