Remove kubectl namespace command
**What this PR does / why we need it**:
It removes deprecated `kubectl namespace` command, which `has been superseded by the context.namespace field of .kubeconfig files. See 'kubectl config set-context --help' for more details`. It was done nearly two years ago, so like `// TODO remove once people have been given enough time to notice` comment says it may be a good time to get rid of it.
**Special notes for your reviewer**:
None ATM.
**Release note**:
<!-- Steps to write your release note:
1. Use the release-note-* labels to set the release note state (if you have access)
2. Enter your extended release note in the below block; leaving it blank means using the PR title as the release note. If no release note is required, just write `NONE`.

CRI: add Message in ContainerStatus
Kubernetes expects a brief CamelCase string as "Reason" and a human-readable
string as "Message" in the conatiner status. It is difficult for kubelet to
derive the other one if the runtime only provides one of the two fields.
Augment the API by adding the "Message" field.

kuberuntime: include container hash in backoff keys

Fix API Installer to generate unique Operation IDs
OperationIDs generated by api_installer.go may not be unique and that causes long auto-generated function names in swagger generated clients. This is a step toward making those IDs unique.

Allow garbage collection to work against different API prefixes
The GC needs to build clients based only on Resource or Kind. Hoist the
restmapper out of the controller and the clientpool, support a new
ClientForGroupVersionKind and ClientForGroupVersionResource, and use the
appropriate one in both places.
Allows OpenShift to use the GC

Remove hacks from ScheduledJobs cron spec parsing
Previusly `github.com/robfig/cron` library did not allow passing cron spec without seconds. First commit updates the library, which has additional method ParseStandard which follows the standard cron spec, iow. minute, hour, day of month, month, day of week.
@janetkuo @erictune as promised in #30227 I've updated the library and now I'm updating it in k8s

oidc authenticator: allow string value as groups claim
Allow the group claim to be a single string instead of an array of
strings. This means the following claim
{
"role": "admin"
}
Will be mapped to the groups

Move HighWaterMark to the top of the struct in order to fix arm, second time
ref: #33117
Sorry for not fixing everyone at once, but I seriously wasn't prepared for that quick LGTM 😄, so here's the other half.
@lavalamp
> lgtm, but seriously, this is terrible, we probably have this bug all over. And what if someone embeds the etcdWatcher struct in something else not at the top? We need the compiler to enforce things like this, it just can't be done manually. Can you file or link a golang issue for this?
I totally agree! There isn't currently a way of programmatically detecting this unfortunately.
I guess @davecheney or @minux can explain better to you why it's so hard.
This is noted in https://github.com/kubernetes/kubernetes/blob/master/docs/proposals/multi-platform.md as a corner case indeed.
@pwittrock This should be cherrypicked toghether with #33117

Fix race condition in setting node statusUpdateNeeded flag
This PR fixes the race condition in setting node statusUpdateNeeded flag
in master's attachdetach controller. This flag is used to indicate
whether a node status has been updated by the node_status_updater or
not. When updater finishes update a node status, it is set to false.
When the node status is changed such as volume is detached or new volume
is attached to the node, the flag is set to true so that updater can
update the status again. The previous workflow has a race condition as
follows
1. updater gets the currently attached volume list from the node which needs to be
updated.
2. A new volume A is attached to the same node right after 1 and set the
flag to TRUE
3. updater updates the node attached volume list (which does not include volume A) and then set the flag to FALSE.
The result is that volume A will be never added to the attached volume
list so at node side, this volume is never attached.
So in this PR, the flag is set to FALSE when updater tries to get the
attached volume list (as in an atomic operation). So in the above
example, after step 2, the flag will be TRUE again, in step 3, updater
does not set the flag if updates is sucessful. So after that, flag is
still TRUE and in next round of update, the node status will be updated.

add resource filter handling before printing
**Release note**:
```release-note
release-note-none
```
Resources are currently filtered (in order to prevent printing) at print
time in their HumanReadablePrinter handlers. This design makes it not
possible to filter objects when they are printed using any other
printer, such as YAML, JSON, or the NamePrinter.
This patch removes any filters previously added at the printer level for
pods and adds a way to define resource-specific filters before they are
sent to a printer handler. A woking filter handler for pods has also been
implemented.
Filters affect resources being printed through the HumanReadablePrinter,
YAML, JSON, and `--template` printers.

unify available api group versions in our scripts
There are currently many parallel lists of available group versions with slightly different syntaxes in each one. This collapses them into a single list for us to maintain.
Also caught spots where the lists didn't match before.

Remove duplicated ECDHE key handling
This PR removes the duplicated ECDHE private key handling. `x509.CreateCertificateRequest` picks the signature type for ECDHE keys already (see https://golang.org/src/crypto/x509/x509.go `signingParamsForPublicKey`). Only the RSA key signature needed customization.
It also defers to `CreateCertificateRequest` to return errors on unknown private key types.
