Check for available volume before attach/delete in EBS
We should check for available volume before performing
attach or delete of EBS volume.
Mutable API calls such as Attach Volume or Delete Volume has much lower quota than immutable API calls such as DescribeVolume or DescribeInstance. Checking for available state before attach or delete
ensures that we are not making useless API calls.

Workloads V1
**What this PR does / why we need it**: This PR promotes the Deployment, ReplicaSet, and DaemonSet StatefulSet, ControllerRevision kinds to the apps/v1 group version.
https://github.com/kubernetes/features/issues/353
**Special notes for your reviewer**:
There will be at least two followups to this PR. The first to add a scale sub-resource when the correct location is resolved, and the second to deal with Conditions in the workloads API.
While it would have been preferable to move the kinds individually providing a lesser burden on reviewers, this proved impracticable due to the intricacies of version resolution in kubectl for objects of the different kinds in the same group.
```release-note
DaemonSet, Deployment, ReplicaSet, and StatefulSet have been promoted to GA and are available in the apps/v1 group version.

kubelet: dockershim: remove orphaned checkpoint files
Fixes https://github.com/kubernetes/kubernetes/issues/55070
Currently, `ListPodSandbox()` returns a combined list of sandboxes populated from both the runtime and the dockershim checkpoint files. However the sandboxes in the checkpoint files might not exist anymore.
The kubelet sees the sandbox returned by `ListPodSandbox()` and determines it shouldn't be running and calls `StopPodSandbox()` on it. This generates an error when `StopContainer()` is called as the container does not exist. However the checkpoint file is not cleaned up. This leads to subsequent calls to `StopPodSandbox()` that fail in the same way each time.
This PR removes the checkpoint file if StopContainer fails due to container not found.
The only other place `RemoveCheckpoint()` is called, except if it is corrupt, is from `RemoveSandbox()`. If the container does not exist, what `RemoveSandbox()` would have done has been effectively been done already. So this is just clean up.

output empty creationTimestamp as null
**Release note**
```release-note
NONE
```
Updates the value of the `creationTimestamp` field to be `null`
when empty, to keep parity between it and `deletionTimestamp`.
Adds a round-trip test to ensure that unstructured objects containing
empty metadata fields are able to be re-converted back into internal
or external objects. Prior to the proposed patch in this PR, an
unstructured object whose `.metadata.creationTimestamp` value had
been set through the metadata accessor to an empty value
(`metav1.Time{}` in this case), was unable to be re-converted to an
internal or external type using the runtime decoder. Conversion would
fail with the error:
```

kube-proxy IPVS: Fix IPVS availability check
**What this PR does / why we need it**:
The current implementation of `CanUseIPVSProxier()` reads `/proc/modules`
to check whether IPVS related kernel modules can be loaded.
You might get a false-negative when the kernel modules are installed to
the system but haven't been loaded into the kernel.
This patch firstly try to run `modprobe` to load specified kernel
modules, then just log warnings if error occured.
Secondly, it will check loaded kernel modules by reading
`/proc/modules`, return an error if any required module is missing.
This change will not break the compatability of existing implementation.
Running kube-proxy in a container without mounting `/lib/modules` will
cause `modprobe` warnings, but not raise an error if all required modules are
present in the host kernel.

+++++++++++++++++++++++++++++++++
* Windows CNI Support
(1) Support to use --network-plugin=cni
(2) Handled platform requirement of calling CNI ADD for all the containers.
(2.1) For POD Infra container, netNs has to be empty
(2.2) For all other containers, sharing the network namespace of POD container,
should pass netNS name as "container:<Pod Infra Container Id>", same as the
NetworkMode of the current container
(2.3) The Windows CNI plugin has to handle this to call into Platform.
Sample Windows CNI Plugin code to be shared soon.
* Sandbox support for Windows
(1) Sandbox support for Windows. Works only with Docker runtime.
(2) Retained CONTAINER_NETWORK as a backward compatibilty flag,
to not break existing deployments using it.
(3) Works only with CNI plugin enabled.
(*) Changes to reinvoke CNI ADD for every new container created. This is hooked up with PodStatus,
but would be ideal to move it outside of this, once we have CNI GET support

kubenet: yield lock while executing CNI plugin.
The CNI plugin can take up to 3 seconds to execute. CNI plugins can safely be
executed in parallel, so yield the lock to speed up pod creation.
This caused problems with the pod latency tests - previously, CNI plugins executed
in under 20ms. Now they must wait for DAD to finish and addresses to leave
tentative state.
Fixes: #54651
**What this PR does / why we need it**:
After upgrading CNI plugins to v0.6 in #51250, the pod latency tests began failing. This is because the plugins, in order to support IPv6, need to wait for DAD to finish. Because this
delay is while the kubenet lock is held, it significantly slows down the pod creation rate.
**Special notes for your reviewer**:
The CNI plugins also do locking for their critical paths, so it is safe to run them concurrently.

Add an import-boss file to inventory what kubectl depends on, so
we can prune this list over time and eventually get kubectl out
of the main k/k repository.
To update this list, You can list the dependencies using:
go list -f '{{ join .Deps "\n"}}' k8s.io/kubernetes/cmd/kubectl | grep
k8s.io/kubernetes | grep -v kubectl | grep -v vendor
Add the generated list of package names to .import-restrictions
file. Then run the hack/verify-import-boss.sh until you have you have
all the packages needed.
Added additional test case that exercises fix#53614 or npe when scaling --replicas=0
Moved creation of clientset and deployment controller objects inside test loop since it's mutated every time an API action happens.

fix azure file mount limit issue on windows due to using drive letter

The current implementation of `CanUseIPVSProxier()` reads `/proc/modules`
to check whether IPVS related kernel modules can be loaded.
You might get a false-negative when the kernel modules are installed to
the system but haven't been loaded into the kernel.
This patch firstly try to run `modprobe` to load specified kernel
modules, then just log warnings if error occured.
Secondly, it will check loaded kernel modules by reading
`/proc/modules`, return an error if any required module is missing.
This change will not break the compatability of existing implementation.
Running kube-proxy in a container without mounting `/lib/modules` will
cause `modprobe` warnings, but not raise an error if all required modules are
present in the host kernel.

make iptables wait flag generic and tune it to 5 seconds
Excerpt from [bug](https://bugzilla.redhat.com/show_bug.cgi?id=1506396) opened by @eparis
> iptables-restore has a 2s wait timeout. Data collected today shows that even with a much faster kernel we can reasonably expect iptables-restore to take upwards of 2.4 seconds. (with unpatched/released RHEL kernel this can easily take 7-8 second)
> longest runs I saw over about 30 minutes were:
> 2.267244
> 2.284707
> 2.291535
> 2.376457
> If we get 2 iptables restores going at the same time, with a 2s timeout it is very likely the second will fail.
> I'd like to suggest a 5s timeout. It should still bound the number of thread we may be waiting on and increases the reliability that a common situation will be automatically resolved without failing up the stack.

Create kubectl's own instance of Scheme and Registry
Create kubectl's own instance of Registry and Scheme.
Switch most command that doesn't depend on internal types to use kubectl's own scheme and register.
There are some hack of registering the internal types in some of unit test now, they should be gone after switch to the external type.
Switch kubectl's factory code to use kubectl's scheme will create a lot of ripples.
I don't want make this PR a super giant PR, so I will do it in a followup PR.
Partially addressed #48564.
Copy the summary from https://github.com/kubernetes/kubernetes/pull/54533#issuecomment-340522302:
- creates pkg/kubectl/scheme (install.go and scheme.go) with
deps on properly vendored k8s.io packages.
- deletes about 80% percent of dependence on pkg/api/legacyscheme
- replaces direct dependence from pkg/kubectl on
pkg/apis/rbac
to a vendor style dependence on
k8s.io/api/rbac
and removes dependencies on rbac paths containing internalversion
- replaces almost 50% of direct dependence on pkg/api with (properly vendored)
k8s.io/api/core/v1
- deletes all of dependence on pkg/apis/policy and k8s.io/api/policy/v1beta1

Fix TestCRD Flake
**What this PR does / why we need it**:
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

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 ...
...
```

```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.
```
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

Shutdown http handlers before shutting down audit backend
**What this PR does / why we need it**:
Currently, audit backend is shut down before http handlers stop processing requests, so some audit events can be dropped in case of batching webhook.

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**.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#54670
This PR fixed the warnning issue mentioned in https://github.com/kubernetes/kubernetes/pull/51252
**Special notes for your reviewer**:
Some values in the code would be like follwoing:
```
GetMountRefs: mountPath ("\\var\\lib\\kubelet\\pods/4c74b128-92ca-11e7-b86b-000d3a36d70c/volumes/kubernetes.io~azure-disk/pvc-1cc91c70-92ca-11e7-b86b-000d3a36d70c")

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.

Ability to do object count quota for all namespaced resources
**What this PR does / why we need it**:
- Defines syntax for generic object count quota `count/<resource>.<group>`
- Migrates existing objects to support new syntax with old syntax
- Adds support to quota all standard namespace resources
- Updates the controller to do discovery and replenishment on those resources
- Updates unit tests
- Tweaks admission configuration around quota
- Add e2e test for replicasets (demonstrate dynamic generic counting)
```
$ kubectl create quota test --hard=count/deployments.extensions=2,count/replicasets.extensions=4,count/pods=3,count/secrets=4
resourcequota "test" created
$ kubectl run nginx --image=nginx --replicas=2
$ kubectl describe quota
Name: test
Namespace: default
Resource Used Hard
-------- ---- ----
count/deployments.extensions 1 2
count/pods 2 3
count/replicasets.extensions 1 4
count/secrets 1 4
```
**Special notes for your reviewer**:
- simple object count quotas no longer require writing code
- deferring support for custom resources pending investigation about how to share caches with garbage collector. in addition, i would like to see how this integrates with downstream quota usage in openshift.
**Release note**:
```release-note
Object count quotas supported on all standard resources using `count/<resource>.<group>` syntax

Remove iptables log on restore failure
Don't log the set of rules at v2 in kube-proxy on error.
The rules are displayed at v5 before the restore is attempted.
In a large cluster the report can generate up to 100000 lines.
A partial report is only helpful if the problem is displayed
in the partial report.
