Add interpretPatchError to return appropriate http code
(400 or 422) according to the error type.
We add this function in apiserver because we don't want
to mention the http code in apimachinery. The apimachinery
code is also used in kubectl. The client should not return
a server error.
Add a test to validate the http error code and error message.

Optimize Repeated registration of AlgorithmProvider when ApplyFeatureGates
**What this PR does / why we need it**:
modified ApplyFeatureGates() just add/del features, cancel the register of all AlgorithmProvider.
there is Repeated registration of all AlgorithmProvider when ApplyFeatureGates() runs;
AlgorithmProvider have already registered when package defaults loaded;
I think ApplyFeatureGates() is just add/del features, it needn't register all AlgorithmProvider again

Support api chunking in kubectl get
This enables chunking in the resource builder to make it easy to
retrieve resources in pages and visit partial result sets. This adds
`--chunk-size` to `kubectl get` only so that users can get comfortable
with the use of chunking in beta. Future changes will enable chunking
for all CLI commands so that bulk actions can be performed more
efficiently.
```
$ kubectl get pods --all-namespaces
... print batch of 500 pods ...
... print second batch of 500 pods ...
...
```
@kubernetes/sig-cli-pr-reviews @kubernetes/sig-api-machinery-pr-reviews
```release-note
`kubectl get` will by default fetch large lists of resources in chunks of up to 500 items rather than requesting all resources up front from the server. This reduces the perceived latency of managing large clusters since the server returns the first set of results to the client much more quickly. A new flag `--chunk-size=SIZE` may be used to alter the number of items or disable this feature when `0` is passed. This is a beta feature.

kubeadm: fix the DNS addon bind address
**What this PR does / why we need it**:
Fixes a small bug introduced in #54437
The net package's definition of `To16` is as follows:
```
// To16 converts the IP address ip to a 16-byte representation.
// If ip is not an IP address (it is the wrong length), To16 returns nil.
func (ip IP) To16() IP {
if len(ip) == IPv4len {
return IPv4(ip[0], ip[1], ip[2], ip[3])
}
if len(ip) == IPv6len {
return ip
}
return nil
}
```
We can see that the `To16 ` function returns a non nil value when passed in an IPv4 address. This PR switches the check to use `To4()` instead, which will return `nil` when passed an IPv6 address.
The DestroyFunc functions returned by generic.NewRawStorage is never
called when we do a StartTestServer() in the test suite. For a quick
hack for now, added TrackStorageCleanup/RegisterStorageCleanup and
CleanupStorage. Note that unless TrackStorageCleanup is called (which
is called only from the test suite) the other two methods are
no-ops essentially. So no change in behavior at runtime. This vastly
brings down the number of goroutines that are left behind when this
test is executed and should reduce if not eliminate the flakiness
of TestCRD

1. We still need to add ResetDefaultDockerProviderExpiration for facilitating tests
2. Do we need a separate image for pulling private image from credential provider?
3. Any suggestion of also adding this for sandbox images? the pause image is a global config of kubelet, but we only need to set a private one for just one test case.

fix warning messages due to GetMountRefs func not implemented in windows
**What this PR does / why we need it**:
This PR completes the windows implementation of GetMountRefs in mount.go. In linux, the GetMountRefs implementaion is: read `/proc/mounts` and find all mount points, while in Windows, there is no such `/proc/mounts` place which shows all mounting points.
There is another way in windows, **we could walk through(by `getAllParentLinks` func) the mount path(symbolic link) and get all symlinks until we got the final device, which is actually a drive**.

Adding an e2e test for admission webhook
Part of https://github.com/kubernetes/features/issues/492
The purpose of this test is making sure the webhooks get called, and the apiserver can communicate with the webhook.
We will expand the test cover more webhook features in followups.
The webhook used in the test rejects pods with container names "webhook-disallow". Will upload the source code of the example in a follow up PR.

Don't log error in getInstanceFromProjectInZoneByName()
**What this PR does / why we need it**:
In function `getInstanceByName()` we attempt to get instance by name from all zones, presumably we might hit multiple not-found errors. Logging every such error seems misleading while debugging.
This PR makes it only logs non not-found errors while getting instance. If eventually no instance is found,
an InstanceNotFound error will be returned as well.
