Switch resourcequota controller to shared informers
Originally part of #40097
I have had some issues with this change in the past, when I updated `pkg/quota` to use the new informers while `pkg/controller/resourcequota` remained on the old informers. In this PR, both are switched to using the new informers. The issues in the past were lots of flakey test failures in the ResourceQuota e2es, where it would randomly fail to see deletions and handle replenishment. I am hoping that now that everything here is consistently using the new informers, there won't be any more of these flakes, but it's something to keep an eye out for.
I also think `pkg/controller/resourcequota` could be cleaned up. I don't think there's really any need for `replenishment_controller.go` any more since it's no longer running individual controllers per kind to replenish. It instead just uses the shared informer and adds event handlers to it. But maybe we do that in a follow up.

This makes it more obvious that they run together and makes the upcoming
rate-limited syncs easier.
Also make test use ints for ports, so it's easier to see when a port is
a literal value vs a name.
This is a weird function, but I didn't want to change any semantics
until the tests are in place. Testing exposed one bug where stale
connections of renamed ports were not marked stale.
There are other things that seem wrong here, more will follow.
Move the feature test to where we are activating the feature, rather
than where we detect locality. This is in service of better tests,
which is in service of less-frequent resyncing, which is going to
require refactoring.

"Avoid unnecessary copies in cacher""
This is resend of #40735 (which I reverted when I suspected it to cause issues). But the issue was a completely different. So it's safe to resubmit.

**What this PR does / why we need it**: the shortcut expander will take the list of short names for resources from the API server during the discovery. For backward compatibility a hardcoded list of short names will always be appended while evaluating a short name.

make kube-aggregator run as static pod for local-up-cluster
Runs the kube-aggregator as a static pod for local-up-cluster. Looks like someone broke kubectl negotiation again, so I'll fix that up separately.
@kubernetes/sig-api-machinery-misc
@lavalamp you're probably looking to run kube-aggregator as a static pod, here's an example.
@jwforres I'll make a secure variant for wiring up to openshift.

Fix AWS device allocator to only use valid device names
According to
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/device_naming.html
we can only use /dev/xvd[b-c][a-z] as device names - so we can only
allocate upto 52 ebs volumes on a node.

apiserver: further cleanup of apiserver storage plumbing
- move kubeapiserver`s `RESTOptionsFactory` back to EtcdOptions by adding a `AddWithStorageFactoryTo`
- factor out storage backend `Config` construction from EtcdOptions
- move all `StorageFactory` related code into server/storage subpackage.
In short: remove my stomach ache about `kubeapiserver.RESTOptionsFactory`.

Isolate recycler behavior in PV E2E
**What this PR does / why we need it**:
Sets the default `reclaimPolicy` for PV E2E to `Retain` and isolates `Recycle` tests to their own context. The purpose of this is to future proof the PV test suite against the possible deprecation of the `Recycle` behavior. This is done by consolidating recycling test code into a single Context block that can be removed en masse without affecting the test suite.
Secondly, adds a liveliness check for the NFS server pod prior to each test to avoid maxing out timeouts if the NFS server becomes unavailable.

[Federation][Kubefed] Bug fix relating kubeconfig path in kubefed init
**What this PR does / why we need it**:
Fixes https://github.com/kubernetes/kubernetes/issues/41305
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
https://github.com/kubernetes/kubernetes/issues/41305
The kubeconfig explicit path is not updated correctly when supplied through the --kubeconfig flag in kubefed init. This leads to the details about the initialised federation control plane not getting updated in the correct kubeconfig file.
**Special notes for your reviewer**:
@madhusudancs
**Release note**:
```
Fixed a bug that caused the kubeconfig entry for the initialized federation control plane to be not written to the supplied kubeconfig file when the file was supplied through the --kubeconfig flag.

Refactored kubemark code into provider-specific and provider-independent parts [Part-3]
Fixes#38967
Applying final part of the changes in PR #39033 (which refactored kubemark code completely). The changes included in this PR are:
- Removed `test/kubemark/common.sh` and moved relevant parts of its code to the right places in start-kubemark/stop-kubemark scripts.
- Added DOCKER_REGISTRY, PROJECT, KUBEMARK_IMAGE_MAKE_TARGET variables to `/test/kubemark/cloud-provider-config.sh` to make the kubemark image push location variable wrt provider.
- Removed get-real-pod-for-hollow-node.sh as it doesn't seem to do anything useful.
