Wait until related e2e and downside plugins are ready.
/hold
**Release note**:
```release-note

Added set and map structural validation for AllowedTopologies
**What this PR does / why we need it**: Adding structural validation to AllowedTopologies field in StorageClass.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#66184
**Release note**:
```release-note
AllowedTopologies field inside StorageClass is now validated against set and map semantics. Specifically, there cannot be duplicate TopologySelectorTerms, MatchLabelExpressions keys, and TopologySelectorLabelRequirement Values.
```
The requested Service Protocol is checked against the supported protocols of GCE Internal LB. The supported protocols are TCP and UDP.
SCTP is not supported by OpenStack LBaaS. If SCTP is requested in a Service with type=LoadBalancer, the request is rejected. Comment style is also corrected.
SCTP is not allowed for LoadBalancer Service and for HostPort. Kube-proxy can be configured not to start listening on the host port for SCTP: see the new SCTPUserSpaceNode parameter
changed the vendor github.com/nokia/sctp to github.com/ishidawataru/sctp. I.e. from now on we use the upstream version.
netexec.go compilation fixed. Various test cases fixed
SCTP related conformance tests removed. Netexec's pod definition and Dockerfile are updated to expose the new SCTP port(8082)
SCTP related e2e test cases are removed as the e2e test systems do not support SCTP
sctp related firewall config is removed from cluster/gce/util.sh. Variable name sctp_addr is corrected to sctpAddr in pkg/proxy/ipvs/proxier.go
cluster/gce/util.sh is copied from master

refuse serviceaccount projection volume request when pod has no servceaccount bounded
**What this PR does / why we need it**:
Currently, if user starts a cluster with ServiceAccount admission plugin disabled, then creates a Pod
like this:
```
kind: Pod
apiVersion: v1
metadata:
labels:
run: nginx
name: busybox2
spec:
containers:
- image: gcr.io/google-containers/nginx
name: nginx
volumeMounts:
- mountPath: /var/run/secrets/tokens
name: token
- image: ubuntu
name: ttt
volumeMounts:
- mountPath: /var/run/secrets/tokens
name: token
command: [ "/bin/bash", "-c", "--" ]
args: [ "while true; do sleep 30; done;" ]
volumes:
- name: token
projected:
sources:
- serviceAccountToken:
path: tokenPath
expirationSeconds: 6000
audience: gakki-audiences
```
The pod creation will fail with error info like:
Events:
```
Type Reason Age From Message
---- ------ ---- ---- -------
Normal Scheduled 23s default-scheduler Successfully assigned office/busybox2 to 127.0.0.1
Warning FailedMount 8s (x6 over 23s) kubelet, 127.0.0.1 MountVolume.SetUp failed for volume "token" : failed to fetch token: resource name may not be empty
```
We should refuse the projection request earlier. This patch fix this.

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.
```

Fixes: #56896
* only report "may not specify more than 1 volume type" once
* fix incorrectly reported field paths
* continue to traverse into projections to report further errors.

explicit kubelet config key in Node.Spec.ConfigSource.ConfigMap
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.
```release-note
You must now specify Node.Spec.ConfigSource.ConfigMap.KubeletConfigKey when using dynamic Kubelet config to tell the Kubelet which key of the ConfigMap identifies its config file.

Resources prefixed with *kubernetes.io/ should remain unscheduled if they are not exposed on the node.
Currently, resources prefixed with `*kubernetes.io/` get scheduled to any
node whether it's exposing that resource or not.
On the other hand, resources prefixed with `someother.domain/` don't get
scheduled to a node until that node is exposing that resource (or if the
resource is ignored because of scheduler extender).
This commit brings the behavior of `*kubernetes.io/` prefixed resources in
line with other extended resources and they will remain unscheduled
until some node exposes these resources.
Fixes#50658
```release-note
Pods requesting resources prefixed with `*kubernetes.io` will remain unscheduled if there are no nodes exposing that resource.

**Release note**:

ACTION REQUIRED: Alpha annotation for PersistentVolume node affinity has been removed. Update your PersistentVolumes to use the beta PersistentVolume.nodeAffinity field before upgrading to this release
```
Currently, resources prefixed with *kubernetes.io/ get scheduled to any
node whether it's exposing that resource or not.
On the other hand, resources prefixed with someother.domain/ don't get
scheduled to a node until that node is exposing that resource (or if the

This commit brings the behavior of *kubernetes.io/ prefixed resources in
line with other extended resources and they will remain unscheduled
until some node exposes these resources.
This also includes renaming IsDefaultNamespaceResource() to
IsNativeResource().
This PR makes the node authorizer automatically set up access rules for
dynamic Kubelet config.
I also added some validation to the node strategy, which I discovered we
were missing while writing this.
