Don't try to write the wrong UID, version on Federated Ingress updates.
Fixes#33135.
This looks more complicated than it really is.
Essentially, use the cluster object's metadata, rather than the federated objects's metadata when updating cluster Ingress objects. The deepcopy stuff is mainly to get around shortcomings in the Kubernetes fake test infrastructure, which ends up with crossed pointers if we don't deep copy.

Fake container exec/logs support for in-process docker CRI integration
This is necessary to unblock other work on docker integration, while we are addressing

remove storage related fields from genericapiserver
Removes `StorageFactory` and `StorageDecorator` from from `genericapiserver` since both constructs are related to building a `RESTStorage`, which should be provided fully formed (or via factory func) to a truly generic API server.
I found this while trying to move the creation API routes earlier.
This is a temporary hack to bypass CRI when getting container logs or
running exec in a container. This is necessary to unblock testing and adding
other features in the integration.

Minor refactor of Ceph RBD provisioning docs.
Improves clarity of Ceph RBD provisioner documentation, expanded on how to translate Ceph settings into secrets.
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
["admin"]
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.
This PR also changes a unit test due to the workflow changes

Apiserver don't log stacktrace when proxying

**What this PR does / why we need it**:
When we are proxying unexpected status from a service or a pod, we print the stack traces (which is not the wanted behaviour). This is an attempt at fixing the issue #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 stack traces.
I'm wrapping the `.Log()` call with an `if` statement to remove all stack traces logging when the call is a proxy from a service or a pod
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.

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.
