Update build documentation about memory required to build Kubernetes on osx to 4.5G
**What this PR does / why we need it**:
To build Kubernetes on osx you now need at least 4.5G of memory configured for Docker.
**Which issue(s) this PR fixes**:
Fixes#62218
**Special notes for your reviewer**:
On an osx I experimented configuring Docker at 0.5GB memory increments. I found that I was unable to successfully build Kubernetes (`make quick-release`) on osx when I configured Docker with 4GB of memory. I was able to build kubernetes after configuring 4.5GB.

apiserver: cancel context on timeout in WithTimeoutForNonLongRunningRequests
Requests that block time out after 60sec, but keep the handler body running. This can lead to exhaustion of clients or other leaks. This PR adds a cancel func to the context of the request and calls it on timeout.
Note: we still do our own timeout handling as we don't trust the context to really cancel every blocking call we do.
This might explain why we see so many handler backtraces like https://gist.github.com/sttts/0ce972dc8a7911e4ca9eea7bf1ded5fa when an etcd node goes down with a hard poweroff. But it does not explain why we see oc to block for 15 minutes.

code-gen: allow specifying custom resync periods for certain informer types
**What this PR does / why we need it**:
This PR extends the informer code-generator to allow the consumer to specify a custom resync period for certain informer types and uses the default resync period if none is defined.
**Special notes for your reviewer**:
Example:
```go
cs := clientset.NewForConfigOrDie(config)
resyncConfig := externalversions.ResyncConfiguration{
&samplev1alpha1.Sample{}: 30 * time.Second,
}
informer := externalversions.NewSharedInformerFactory(cs, 2*time.Minute, externalversions.WithCustomResyncConfig(resyncConfig))

Migrating test images to gcr.io/kubernetes-e2e-test-images
**What this PR does / why we need it**:
Currently e2e test images are distributed between 2 different registry locations, k8s.gcr.io and gcr.io/kubernetes-e2e-test-images. This is part of a multi-step initiative to house all the images in gcr.io/kubernetes-e2e-test-images.

1. I am starting off with migrating images under k8s/test/images/volumes-tester.
2. I did not move ceph and nfs images since they are marked for [deprecation and removal](https://github.com/kubernetes/kubernetes/tree/master/test/images/volumes-tester). Let me know if we want them moved as well.
3. I have made a copy of the images in gcr.io/kubernetes-e2e-test-images so the references are not broken post the PR merge. Will work on removing the images from k8s.gcr.io once this change sticks.

sample-controller: add status subresource support
Builds on top of https://github.com/kubernetes/kubernetes/pull/55168.
**DO NOT MERGE** until https://github.com/kubernetes/kubernetes/pull/55168 is merged. Adding a hold.
/hold
Update: It is now merged! 🎉
This PR:
- Adds an example to show how to use the `/status` subresource with custom resources.
- Generates `UpdateStatus` for the `Foo` resource.
- Updates the comment in the controller to mention that `UpdateStatus` can now be used. Note: this is not enabled by default because subresources require the feature gate to be enabled and are not on by default.
- Updates the README to add feature gate information and examples for `CustomResourceSubresources`.
- Updates the README to remove feature gate information for CRD validation since the current example uses `apps/v1` deployments (and thus requires v1.9 anyway).

Schedule even if extender is not available when using extender
**What this PR does / why we need it**:
When using scheduler extender, if the extender is not available scheduling of all pods fail.
We should let the scheduling happen but display error message that extender is failing.
`IsIgnorable()` is added to extender to indicate: if scheduling of all pods should fail when it's unavailable
**Backward compabtiility:**
We use `IsIgnorable` instead of `IsCritical` so that when this flag is not set, the default value will be `false`, i.e. not ignorable, which consistent with the current behavior in existing extenders.
