Refactor cert utils into one pkg, add funcs from bootkube for kubeadm to use
**What this PR does / why we need it**:
We have ended-up with rather incomplete and fragmented collection of utils for handling certificates. It may be worse to consider using `cfssl` for doing all of these things, but for now there is some functionality that we need in `kubeadm` that we can borrow from bootkube. It makes sense to move the utils from bookube into core, as discussed in #31221.
**Special notes for your reviewer**: I've taken the opportunity to review names of existing funcs and tried to make some improvements in that area (with help from @peterbourgon).
**Release note**:
```release-note
NONE

simplify RC and SVC listers
Make the RC and SVC listers use the common list functions that more closely match client APIs, are consistent with other listers, and avoid unnecessary copies.
This commit moves away from using a global variable for default
configuration checking, and instead exposes a method on LoadingRules to
determine whether a particular restclient.Config should be considered
"default". This allows kubectl to provide its own defaults (the same
as before, KUBERNETES_MASTER and the static localhost:8080 values) while
allowing other clients to avoid defining them.
In-cluster config defaulting is now easier to read.

Add storage api group to hack/update-codegen.sh
Add it to the script then run it in the second commit. 1.4 needs the same change, I'll do it in my other PR.

Check init containers in PodContainerRunning
Sometimes when an init container runs and terminates quickly, PodContainerRunning can go into a
state where the pod indicates it's still running, but the container is already terminated. Handle
that condition by returning ErrContainerTerminated when it happens.

Switch ScheduledJob controller to use clientset
**What this PR does / why we need it**:
This is part of #25442. I've applied here the same fix I've applied in the manual client in #29187, see the 1st commit for that (@caesarxuchao we've talked about it in #29856).

Handle Stream() errors consistently in restclient
We should be following the same rules for Stream() as the normal body
request flow.
Also add slightly more output on a server error - in the future we may
want to clean this up but it's potentially hiding bad responses.
Related to #32009 but isn't the fix (so far)

Fix clientcmd for a non-host cluster client running in a pod.
This is based on @errordeveloper's PR #32438. It fixes a case where default config is invalid and original config, i.e. `mergedConfig` is empty. It also adds a test for the case where default config is invalid and original config is neither invalid nor empty.

Allow namespace to be loaded from in-cluster config
This is a follow on from the previous commit that fixed ClientConfig.
Namespace can also be defaulted from ICC, and this correctly handles
that logic. Also add two debugging lines to ensure that it is easier in
the future to uncover problems here.
Fixes#32352

Add a check in ConfirmUsable() to validate the contextName
**What this PR does / why we need it**:
When a context name is provided, but can't be found (miss spelling), it currently
uses the defaults. This PR will cause the command to fail, to prevent unexpected side effects
of using the wrong configuration.
**Which issue this PR fixes**
fixes#21062
**Special notes for your reviewer**:
None
**Release note**:
```release-note
Error if a contextName is provided but not found in the kubeconfig.

Example of unversioned pkg uses correct Config struct
Currently this Doc has incorrect example - https://godoc.org/k8s.io/kubernetes/pkg/client/unversioned
So when developers use it they are confused why `client` pkg has no `Config` struct, actually this is a struct from `restclient` pkg.
Also pkg name and variable name should be equal:
`client, err := client.New(config)`
Thanks,
Alex
Changes made in #31947 cause kube-proxy to ignore `--kubeconfig`
and `--master` flags and use in-cluster configuration, which is
unusable due to the fact that VIP hasn't been created yet.
This is a follow on from the previous commit that fixed ClientConfig.
Namespace can also be defaulted from ICC, and this correctly handles
that logic. Also add two debugging lines to ensure that it is easier in
the future to uncover problems here.
