Make admission webhooks conversion convert CONNECT body correctly
Fix#59759.
1. Make apiserver pass connectRequest.Options directly to the admission layer. All other information in rest.ConnectRequest is present in admission attributes.
2. Make the scope.Kind of pod/attach, pod/exec, pod/portforward, node/proxy, service/proxy to their respective options Kind, instead of the parent Kind.
I've tested it locally, the conversion is working correctly for "kubectl attach". I'll add e2e tests.
I'll keep this to myself until I add the tests, but cc @mikedanese @liggitt RE. https://github.com/kubernetes/kubernetes/pull/66633.

Update openapi and doc to reflect 202 path in API server delete handler
**What this PR does / why we need it**:
Our API server returns 202 Accepted if a delete operation is asynchronous, but it is not reflected in our openapi spec and documentation. This PR adds 202 path in endpoint installer and updates our openapi spec and docs. The change in openapi spec may affect some clients that depend on the error paths. [Python client](e057f27306/kubernetes/client/api_client.py (L97-L102)) only depends on response type, which is not changed in this PR. Sending this PR to see if it breaks client-go.

Fixing comments in types.go to describe the changes for CSI driver default FS type override fix
This PR fixes the comment in types.go which was made in the commit 5dfe7b5758
In the above commit, the change that fixed the override of default FSType for CSI driver was made. However the comments in types.go were made for GCEPersistentDiskVolumeSource and RBDVolumeSource respectively. This commit fixes that comment to reflect the changes for CSI driver

Bugfix/csi default fs type
This PR address the issue mentioned in the following ticket https://github.com/kubernetes/kubernetes/issues/65122
The FSType string will now not be defaulted to ext4. Removes defaulting of CSI file system type to ext4. CSI plugins that depended on this default need to be updated as the fsType would remain an empty string if not provided and would not default to ext4. CSI spec allows for an empty fstype string. This is intended for non-block plugins like nfs and gluster where filesystems are not separately created on the volume. But currently the default file system is overridden to ext4 which makes the above case redundant. This commit prevents such an overridding.
```release-note
ACTION REQUIRED: Removes defaulting of CSI file system type to ext4. All the production drivers listed under https://kubernetes-csi.github.io/docs/Drivers.html were tested and work as expected after this change. If you are using a driver not in that list, please test the drivers on an updated test cluster first. ```

core v1: deprecate the gitRepo volume type
gitRepo stopped accepting new features nearly 2 years ago https://github.com/kubernetes/kubernetes/issues/17676#issuecomment-228650586 and today this behavior can easily be achieved through an init container. The kubelet shelling out to git in the host namespace can also be a security issue on un-trusted repos, as was demonstrated by [CVE-2017-1000117](https://groups.google.com/forum/#!topic/kubernetes-announce/CTLXJ74cu8M). Our own documentation even alludes to this volume type being removed in the future:
> In the future, such volumes may be moved to an even more decoupled model, rather than extending the Kubernetes API for every such use case.
https://kubernetes.io/docs/concepts/storage/volumes/#gitrepo
Closes https://github.com/kubernetes/kubernetes/issues/60999
```release-note-action-required
The GitRepo volume type is deprecated. To provision a container with a git repo, mount an EmptyDir into an InitContainer that clones the repo using git, then mount the EmptyDir into the Pod's container.
```
/release-note-action-required
Instead of this:
```yaml
apiVersion: v1
kind: Pod
metadata:
name: server
spec:
containers:
- image: nginx
name: nginx
volumeMounts:
- mountPath: /mypath
name: git-volume

revision: "22f1d8406d464b0c0874075539c1f2e96c253775"
```
Do this:
```yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: git-clone
data:
git-clone.sh: |
#!/bin/sh -e
git clone $1 $3
cd $3

Move to a structured status for dynamic kubelet config
This PR updates dynamic Kubelet config to use a structured status, rather than a node condition. This makes the status machine-readable, and thus more useful for config orchestration.
Fixes: #56896
```release-note
The status of dynamic Kubelet config is now reported via Node.Status.Config, rather than the KubeletConfigOk node condition.
```
Updates dynamic Kubelet config to use a structured status, rather than a
node condition. This makes the status machine-readable, and thus more
useful for config orchestration.
Fixes: #56896
This makes the Kubelet config key in the ConfigMap an explicit part of
the API, so we can stop using magic key names.
As part of this change, we are retiring ConfigMapRef for ConfigMap.
