Wait for server resources.
For https://github.com/kubernetes/kubernetes/issues/55768.
In e2e test for containerd, I sometimes see the following fail (e.g. https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-cri-containerd-e2e-gci-gce/178):
```
Nov 15 02:40:31.291: Couldn't delete ns: "e2e-tests-container-probe-dcvlw": unable to retrieve the complete list of server APIs: metrics.k8s.io/v1beta1: the server could not find the requested resource (&discovery.ErrGroupDiscoveryFailed{Groups:map[schema.GroupVersion]error{schema.GroupVersion{Group:"metrics.k8s.io", Version:"v1beta1"}:(*errors.StatusError)(0xc420bfd170)}})

Usually, only the first few tests fail with this error. The error seems to be returned at this line https://github.com/kubernetes/kubernetes/blob/master/test/e2e/framework/util.go#L1170.

code-generator: complete PkgName, GroupName, GoName seperation
... in client-gen, informer-gen, lister-gen. Follow-up of https://github.com/kubernetes/kubernetes/pull/54950.
Before this PR, the generated code was broken for internal types and for group package names that were no valid Go identifiers.
This PR completes the separation in the following sense:
- GroupNames are domain-like logical name for the group. Only the first segment is used as default for GoName
- PkgName is the directory name. All packages in client, informer, lister re-use this for packages.
- GoName is the Go identifier (CamelCase) used to reference the group, e.g. in the interface names, in the clientsets etc. Moreover it is used for package import aliases.
Note: this PR **does not** change the generated code in Kubernetes, only the examples in k8s.io/code-generator.
```release-note
Fix code-generators to produce correct code when GroupName, PackageName and/or GoName differ.

Enhance label and taint documentation in kubectl
**What this PR does / why we need it**:
This adds some language around how taint and label keys can have a domain + '/' in front of them. From the current documentation, it would seem like these are not allowed even though [well known labels](https://kubernetes.io/docs/reference/labels-annotations-taints/) have them.
Also, it seemed unclear (to me) that both the label's key and value can be 63 characters long. I wanted to clarify this.
