The tests for Downward API volume were apparently created before the
default sync-frequency was set to 1 minute. As the current
implementation of Pod gives us no guarantee that the changes will be
seen in Downward API before `sync-frequency` we need the tests to
reflect this.
Fixes: #29633

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

move registry packages for all API groups
This continues the pattern of `registry/<group>/resource` for our backing storage. This entire pull is nothing but moves. I'll reswizzle the actual storage next, but these are cargo-culted everywhere, so I want to lay this down early.

This allows runtimes in different packages (dockertools, rkt, kuberuntime) to
share the same logic. Before this change, only dockertools support this
feature. Now all three packages support image pull throttling.

Additional timeouts are proven unnecessary, the problem lies with the cpu limits
The default core_pattern pipes the core dumps to /sbin/crash_reporter
which is more restrictive in saving crash dumps. So for
now, set a generic core_pattern that users can work with.
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.

Fix possible panic in PodAffinityChecker
In `PodAffinityChecker.getMatchingAntiAffinityTerms()` `affinity.PodAntiAffinity` can be `nil` in this place. This problem occurs e.g. when `nil` is passed as `meta` to `PodAffinityChecker.InterPodAffinityMatches()`.
Stumbled upon it while working on #31136 (someone PTAL at that PR too, I've submitted it a month ago and seemingly no one noticed it), kube-controller-manager was crashing there.

compensate for raft/cache delay in namespace admission
When attempting to create an object in a just-created namespace, the admission plugin can reject the creation attempt for two reasons:
1. The cache of existing namespaces has not observed the creation watch event yet. There was already compensation to perform a live lookup if the namespace was not found in the cache.
2. The live lookup can be performed against a non-leader in a HA etcd setup, and can return NotFound if the non-leader etcd has not observed the creation.
This PR adds a delay, then rechecks the cache before proceeding with the live lookup. This gives both the cache and the backing storage more time to observe the create, before failing the request.
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.
