Send recycle events from pod to pv.
This allows users to diagnose what's wrong with recycler. Recycler pods are started automatically with a cryptic name and they are deleted immediately when they finish.
e.g, `kubectl describe pv` could show that NFS cannot be mounted (and how many pods have tried it):

These steps were necessary:
- added event watcher to volume.RecycleVolumeByWatchingPodUntilCompletion
- pass all these events through volume plugins to volume controller
- rework volume.RecycleVolumeByWatchingPodUntilCompletion unit tests to a table (too much copy-paste)
- fix all unit tests along the way
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.

Node E2E: Change the disk eviction test to pull images again after the test.
Fixes https://github.com/kubernetes/kubernetes/issues/32022#issuecomment-248677706.

Attempt at closing #32747,
With the `RequestInfoResolver` struct, it's possible to inspect the
request and get the `Verb`. In this case, the `proxy` value is what I
was looking for to avoid logging stacktraces.
I'm wrapping the `.Log()` call with an `if` statement to remove all
stacktrace logging when we proxied through the apiserver
Another approach would have been to add another kind of
`StacktracePred` in the `httplog` package. I found this path to be
trickier to code as it's currently only accepting int values.

Fix FakeNodeHandler Update behaviour
Two problems:
1. Get is always using Existing nodes slice, and you will for sure miss any updated data
2. Each Update adds a duplicate node entry to UpdatedNodes slice
For the 1st, we will try to find a node in UpdatedNodes slice (same as for the List).
2nd - append only if there is no node with same name as updated, if there is we will replace object in UpdatedNodes slice.

Correct versioned.Event output in Swagger
Fixes#24240
```release-note
The value of the `versioned.Event` object (returned by watch APIs) in the Swagger 1.2 schemas has been updated from `*versioned.Event` which was not expected by many client tools. The new value is consistent with other structs returned by the API.

Move image pull throttling logic to pkg/kubelet/images

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.

*Problem*
issues like https://github.com/kubernetes/kubernetes/pull/32384/ happen because we dont compile the integration tests as part of the build
*Solution*
This pr will make it so scheduler_perf is included in the integration tests, but it will run in short mode that only makes sure compilation happens . it also removes the over generalized test/component directory which only has one entry
```
test/integration/replicationcontroller
test/integration/scheduler

test/integration/scheduler_perf

Remove closing audit log file and add error check when writing to audit
This picks the order fix from #33164. Additionally I've removed entirely closing the log file, since it didn't make sense where it was. I've also added error checks when actually writing to audit logs.
@sttts ptal
**1.4 justification:**
Risk: the code only runs if auditing is enabled with an apiserver flag. So the risk is low.
Rollback: nothing should depend on this
Cost: the auditing feature is broken because the impersonation filter is applied before and you might not see the proper user when using `--as` flag. Additionally no errors are logged if writing to audit fails.
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.
