Add links to issues referenced in some design documents
Add link to issues referenced in `nodeaffinity.md` and `podaffinity.md`. It would be helpful to visit the issue directly. Also fix broken format of `podaffinity.md` when # is at the beginning of a line.

Make GKE detect-instance-groups work on Mac.
Make the fix from #27803 also work on mac.
The GNU `expr` command supports both the `expr match STRING REGEXP` and `expr STRING : REGEXP` command syntax.
The BSD `expr` command only has the `expr STRING : REGEXP` syntax.

Add MinReadySeconds to rolling updater
Add MinReadySeconds support to RollingUpdater that allows to specify the number of seconds to wait on top of the pod is "ready" because its readiness probe passed.
Summarized what I thought were the most interesting changes for
all users, and for specific cloud providers.
Still need better list of breaking changes.

Add additional testing scenarios for compute resource requests=0
I was asked about the qos tier of a pod that specified
`--requests=cpu=0,memory=0 --limits=cpu=100m,memory=1Gi`
and in just investigating current behavior, realized we should have an explicit test case to ensure that 0 values are preserved in defaulting passes, and that this is still a burstable pod (but the lowest for that tier as it related to eviction)

This commit includes a proposal and a Go file to re-define the container
runtime interface.
Note that this is an experimental interface and is expected to go through
multiple revisions once developers start implementing against it. As stated in
the proposal, there are also individual issues to carry discussions of
specific features.

Update "kubectl get all" to display resource type as part of name
fixes#23838
release-note-none
When running "kubectl get all", or printing any output with mixed resource kinds, an additional column is added to the output with each resource's kind:
`kubectl get all --all-namespaces`
```

testproject rc/node-1 0 0 2d

kubectl: don't display an empty list when trying to get a single resource that isn't found
Return immediately when attempting to get a singular resource that isn't found, so that we avoid
printing out a List if the output format is something like json or yaml.
Before:
```
$ kubectl get pod/foo -o yaml
apiVersion: v1
items: []
kind: List
metadata: {}
pods "foo" not found
```
After:
```
$ kubectl get pod/foo -o yaml
pods "foo" not found
```

Fix node confomance test
Fixes https://github.com/kubernetes/kubernetes/issues/28255, https://github.com/kubernetes/kubernetes/issues/28250, https://github.com/kubernetes/kubernetes/issues/28341.
The main reason of the flake is that in the failed test expects the `PodPhase` to keep `Pending`. It did `Eventually` check and `Consistently` check for 5 seconds. However, the default `PodPhase` is `Pending`, when the check passes, the `PodStatus` could still be in default state.
After that, the test expects the container status to be `Waiting`, which may not be the case, because the default `ContainerStatuses` is empty, and the pod could still be in the default state.
This PR changes the test to ensure `ContainerStatuses` first and then check the `PodPhase` after that.
Mark P1 because the test fails relatively frequently and does block some PRs.

Allow specifying secret data using strings
This PR allows specifying non-binary data values in `Secret` objects as `"stringData":{"key":"string value"}`, in addition to the existing base64 []byte serializations in the `data` field.
On write, the keys and values in the `stringData` field are merged to the `data` map, overwriting any values already present in the `data` map. The move is one-way, the `stringData` field is never output when reading from the API.
A Secret could be created like this:
```
{
"kind":"Secret",
"apiVersion":"v1",
"metadata":{"name":"mysecret"},
"data":{
"image":"<base64-encoded-jpg>"
},
"stringData":{
"username": "myuser",
"password": "mypassword"
}
}
```
and when read from the API would look like this:
```
{
"kind":"Secret",
"apiVersion":"v1",
"metadata":{"name":"mysecret",...},
"data":{
"image":"<base64-encoded-jpg>"
"username": "bXl1c2Vy",
"password": "bXlwYXNzd29yZA=="
}
}

Use slices of items to clean up after tests
Fixes#27582.
We used to maintain a pointer variable for each process to kill after the
tests finish. @lavalamp suggested using a slice instead, which is a much
cleaner solution. This implements @lavalamp's suggestion and also extends
the idea to tracking directories that need to be removed after the tests finish.
This also means that we should no longer check for nil `killCmd`s inside
`func (k *killCmd) Kill() error {...}` (see #27582 and #27589). If a nil
`killCmd` makes it in there, something is bad elsewhere and we want to see
the nil pointer exception immediately.
Mentioning @timstclair and @euank wrt the original issue/PR.

Should set default value for --service-node-port-range flag before verifying
For the flag `--service-node-port-range` of kube-apiserver, we know that it defaults to `30000-32767` if not specified. But if we only pass the flag `--kubernetes-service-node-port` with a valid value between `30000-32767` when starting kube-apiserver, a fatal error will occurs as the last below. It means that service port range is not 30000-32767 but empty. The log is from code [DefaultAndValidateRunOptions-->ValidateRunOptions-->verifyServiceNodePort](https://github.com/xiangpengzhao/kubernetes/blob/master/pkg/genericapiserver/genericapiserver.go#L580) where the flags are verified.
After tracing the apiserver related code, we can find the call stack:
```
func main() {
......
s := options.NewAPIServer()
......
app.Run(s)
......
}
```
In the `app.Run`, it calls [genericapiserver.DefaultAndValidateRunOptions(s.ServerRunOptions)](https://github.com/xiangpengzhao/kubernetes/blob/master/cmd/kube-apiserver/app/server.go#L80). But the `--kubernetes-service-node-port` hasn't been defaulted before there, so it's empty. It's then defaulted in `app.Run`-->[master.New](https://github.com/xiangpengzhao/kubernetes/blob/master/cmd/kube-apiserver/app/server.go#L276)-->[genericapiserver.New](https://github.com/xiangpengzhao/kubernetes/blob/master/pkg/master/master.go#L179)-->[setDefaults](https://github.com/xiangpengzhao/kubernetes/blob/master/pkg/genericapiserver/genericapiserver.go#L338)-->[defaultServiceNodePortRange](https://github.com/xiangpengzhao/kubernetes/blob/master/pkg/genericapiserver/genericapiserver.go#L281).
So, we have to set default value for `--kubernetes-service-node-port` in [NewServerRunOptions](https://github.com/xiangpengzhao/kubernetes/blob/master/pkg/genericapiserver/options/server_run_options.go#L105), as is done for `--secure-port` and/or `--insecure-port`. The `NewServerRunOptions` will be called in options.[NewAPIServer](https://github.com/xiangpengzhao/kubernetes/blob/master/cmd/kube-apiserver/app/options/options.go#L50)().
Hope that I have described the issue clearly. Thanks!

Implement custom help command for kubectl
```release-note
* kubectl help now provides "Did you mean this?" suggestions for typo/invalid command names.
```
Custom implementation of help command allows to print `Did you mean this?` with
suggestions, which is missed in embed help command from github.com/spf13/cobra
Also, it can be extended with different search features. At this patch, help
command searches query in short descriptions of commands in case of mismatch
with commands names.
