enhance unit tests of advance audit feature
This change addresses comments from @crassirostris
https://github.com/kubernetes/kubernetes/pull/49115#discussion_r133416080
It does three things:
1. use auditinternal for unit test in filter stage
2. add a seperate unit test for Audit-ID http header
3. add unit test for audit log backend
**Release note**:
```
NONE
```
Charge object count when object is created, no matter if the object is
initialized or not.
Charge the remaining quota when the object is initialized.
Also, checking initializer.Pending and initializer.Result when
determining if an object is initialized. We didn't need to check them
because before 51082, having 0 pending initializer and nil
initializers.Result is invalid.

Graduate metrics/v1alpha1 to v1beta1
This introduces v1beta1 of the resource metrics API, previously in alpha.
The v1alpha1 version remains for compatibility with the Heapster legacy version
of the resource metrics API, which is compatible with the v1alpha1 version. It also
renames the v1beta1 version to `resource-metrics.metrics.k8s.io`.
The HPA controller's REST clients (but not the legacy client) have been migrated as well.
Part of kubernetes/features#118.
```release-note
Migrate the metrics/v1alpha1 API to metrics/v1beta1. The HorizontalPodAutoscaler
controller REST client now uses that version. For v1beta1, the API is now known as
resource-metrics.metrics.k8s.io.

Update Cadvisor Dependency
Fixes: https://github.com/kubernetes/kubernetes/issues/51832
This is the worst dependency update ever...
The root of the problem is the [name change of Sirupsen -> sirupsen](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276). This means that in order to update cadvisor, which venders the lowercase, we need to update all dependencies to use the lower-cased version. With that being said, this PR updates the following packages:
`github.com/docker/docker`
- `github.com/docker/distribution`
- `github.com/opencontainers/go-digest`
- `github.com/opencontainers/image-spec`

Add client side event spam filtering
**What this PR does / why we need it**:
Add client side event spam filtering to stop excessive traffic to api-server from internal cluster components.
this pr defines a per source+object event budget of 25 burst with refill of 1 every 5 minutes.
i tested this pr on the following scenarios:
**Scenario 1: Node with 50 crash-looping pods**
```
$ create 50 crash-looping pods on a single node
$ kubectl run bad --image=busybox --replicas=50 --command -- derekisbad
```
Before:
* POST events with peak of 1.7 per second, long-tail: 0.2 per second
* PATCH events with peak of 5 per second, long-tail: 5 per second
After:
* POST events with peak of 1.7 per second, long-tail: 0.2 per second
* PATCH events with peak of 3.6 per second, long-tail: 0.2 per second
Observation:
* https://github.com/kubernetes/kubernetes/pull/47462 capped the number of total events in the long-tail as expected, but did nothing to improve total spam of master.
**Scenario 2: replication controller limited by quota**
```
$ kubectl create quota my-quota --hard=pods=1
$ kubectl run nginx --image=nginx --replicas=50
```
Before:
* POST events not relevant as aggregation worked well here.
* PATCH events with peak and long-tail of 13.6 per second
After:
* POST events not relevant as aggregation worked well here.
* PATCH events with peak: .35 per second, and long-tail of 0
**Which issue this PR fixes**
fixes https://github.com/kubernetes/kubernetes/issues/47366
**Special notes for your reviewer**:
this was a significant problem in a kube 1.5 cluster we are running where events were co-located in a single etcd. this cluster was normal to have larger numbers of unhealty pods as well as denial by quota.

Allow custom client verbs to be generated using client-gen
This change will allow to define custom verbs for resources using the following new tag:
```
// +genclient:method=Foo,verb=create,subresource=foo,input=Bar,output=k8s.io/pkg/api.Blah
```
This will generate client method `Foo(bar *Bar) (*api.Blah, error)` (format depends on the particular verb type)
With this change we can add `UpdateScale()` and `GetScale()` into all scalable resources. Note that intention of this PR is not to fix the Scale(), but that is used as an example of this new capability.
Additionally this will also allow us to get rid of `// +genclient:noStatus` and fix guessing of the "updateStatus" subresource presence based on the existence of '.Status' field.
Basically you will have to add following into all types you want to generate `UpdateStatus()` for:
```
// +genclient:method=UpdateStatus,verb=update,subresource=status
```
This allows further extension of the client without writing an expansion (which proved to be pain to maintain and copy...). Also allows to customize native CRUD methods if needed (input/output types).

Mount propagation in kubelet
Together with #45724 it implements mount propagation as proposed in https://github.com/kubernetes/community/pull/659
There is:
- New alpha annotation that allows user to explicitly set propagation mode for each `VolumeMount` in pod containers (to be replaced with real `VolumeMount.Propagation` field during beta) + validation + tests. "Private" is the default one (= no change to existing pods).
I know about proposal for real API fields for alpha feature in https://docs.google.com/document/d/1wuoSqHkeT51mQQ7dIFhUKrdi3-1wbKrNWeIL4cKb9zU/edit, but it seems it's not implemented yet. It would save me quite lot of code and ugly annotation.
- Updated CRI API to transport chosen propagation to Docker.
- New `kubelet --experimental-mount-propagation` option to enable the previous bullet without modifying types.go (worked around with changing `KubeletDeps`... not nice, but it's better than adding a parameter to `NewMainKubelet` and removing it in the next release...)
```release-note
kubelet has alpha support for mount propagation. It is disabled by default and it is there for testing only. This feature may be redesigned or even removed in a future release.

add information for subresource kind determination
xref https://github.com/kubernetes/kubernetes/issues/38810https://github.com/kubernetes/kubernetes/issues/38756
Polymorphic subresources usually have different groupVersions for their discovery kinds than their "native" groupVersions. Even though the APIResourceList shows the kind properly, it does not reflect the group or version of that kind, which makes it impossible to unambiguously determine if the subresource matches you and it is impossible to determine how to serialize your data. See HPA controller.
This adds an optional Group and Version to the discovery doc, which can be used to communicate the "native" groupversion of an endpoint. Doing this does not preclude fancier contenttype negotiation in the future and doesn't prevent future expansion from indicating equivalent types, but it does make it possible to solve the problem we have today or polymorphic categorization.

```release-note
Adds optional group and version information to the discovery interface, so that if an endpoint uses non-default values, the proper value of "kind" can be determined. Scale is a common example.

Kubectl to use http caching to cache openapi responses from the server
**What this PR does / why we need it**:
This PR is trying to address the problems raised in #50254
> * uses a disk-based cache that is not safe between processes (does not use atomic fs operations)
> * writes get/list responses to disk that should not be cached (like kubectl get secrets)
> * is vulnerable to partially written cache responses being used as responses to future requests
> * breaks uses of the client transport that make use of websockets
> * defaults to enabling the cache for any client builder using RecommendedConfigOverrideFlags or DefaultClientConfig which affects more components than just kubectl
All of these points are addressed by this pull-request:
1. It now uses atomic fs operations
2. Doesn't cache by default, only if requested by the client (and it's only done by openapi client)
3. Fixed because of atomic fs operations
4. Found the reason for the bug: Cache wrapper couldn't be unwrapped. I implemented the `WrappedRoundTripper` interface.
5. Since 2. is fixed, I think that should be fine

Add Google cloud KMS service for envelope encryption transformer
This adds the required pieces which will allow addition of KMS based encryption providers (envelope transformer).
For now, we will be implementing it using Google Cloud KMS, but the code should make it easy to add support for any other such provider which can expose Decrypt and Encrypt calls.
Writing tests for Google Cloud KMS Service may cause a significant overhead to the testing framework. It has been tested locally and on GKE though.
Upcoming after this PR:
* Complete implementation of the envelope transformer, which uses LRU cache to maintain decrypted DEKs in memory.
* Track key version to assist in data re-encryption after a KEK rotation.

Feature gate initializers field
The metadata.initializers field should be feature gated and disabled by default while in alpha, especially since enforcement of initializer permission that keeps users from submitting objects with their own initializers specified is done via an admission plugin most clusters do not enable yet.
Not gating the field and tests caused tests added in https://github.com/kubernetes/kubernetes/issues/51429 to fail on clusters that don't enable the admission plugin.
This PR:
* adds an `Initializers` feature gate, auto-enables the feature gate if the admission plugin is enabled
* clears the `metadata.initializers` field of objects on create/update if the feature gate is not set
* marks the e2e tests as feature-dependent (will follow up with PR to test-infra to enable the feature and opt in for GCE e2e tests)
```release-note
Use of the alpha initializers feature now requires enabling the `Initializers` feature gate. This feature gate is auto-enabled if the `Initialzers` admission plugin is enabled.

Fix mergekey of initializers; Repair invalid update of initializers
Fix https://github.com/kubernetes/kubernetes/issues/51131
The PR did two things to make parallel patching `metadata.initializers.pending` possible:
* Add mergekey to initializers.pending
* Let the initializer admission plugin set the `metadata.intializers` to nil if an update makes the `pending` and the `result` both nil, instead of returning a validation error. Otherwise if multiple initializer controllers sending the patch removing themselves from `pending` at the same time, one of them will get a validation error.
```release-note
The patch to remove the last initializer from metadata.initializer.pending will result in metadata.initializer to be set to nil (assuming metadata.initializer.result is also nil), instead of resulting in an validation error.

Remove null -> [] slice hack
Closes#44593
When 1.6 added protobuf storage, the storage layer lost the ability to persist slice fields with empty but non-null values.
As a workaround, we tried to convert empty slice fields to `[]`, rather than `null`. Compressing `null` -> `[]` was just as much of an API breakage as `[]` -> `null`, but was hoped to cause fewer problems in clients that don't do null checks.
Because of conversion optimizations around converting lists of objects, the `null` -> `[]` hack was discovered to only apply to individual get requests, not to a list of objects. 1.6 and 1.7 was released with this behavior, and the world didn't explode. 1.7 documented the breaking API change that `null` and `[]` should be considered equivalent, unless otherwise noted on a particular field.
This PR:
* Reverts the earlier attempt (https://github.com/kubernetes/kubernetes/pull/43422) at ensuring non-null json slice output in conversion
* Makes results of `get` consistent with the results of `list` (which helps naive clients that do deepequal comparisons of objects obtained via list/watch and get), and allows empty slice fields to be returned as `null`
```release-note
Protobuf serialization does not distinguish between `[]` and `null`.
API fields previously capable of storing and returning either `[]` and `null` via JSON API requests (for example, the Endpoints `subsets` field) can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6+). JSON API clients should tolerate `null` values for such fields, and treat `null` and `[]` as equivalent in meaning unless specifically documented otherwise for a particular field.

Paramaterize `stickyMaxAgeMinutes` for service in API
**What this PR does / why we need it**:
Currently I find `stickyMaxAgeMinutes` for a session affinity type service is hard code to 180min. There is a TODO comment, see
https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/iptables/proxier.go#L205
I think the seesion sticky max time varies from service to service and users may not aware of it since it's hard coded in all proxier.go - iptables, userspace and winuserspace.
Once we parameterize it in API, users can set/get the values for their different services.
Perhaps, we can introduce a new field `api.ClientIPAffinityConfig` in `api.ServiceSpec`.
There is an initial discussion about it in sig-network group. See,

default field selectors
We have a lot of code around field selectors that doesn't add much value. Every gettable resources probably wants name and namespace by default and since they all use metav1 (today), we can assign that as a default. If we think we'll always have metav1 style name and namespace, then this makes a reasonable default and you can always set something different.
This removes cruft and avoids the risk of accidentally forgetting a field selector.

2. While updating the CRD:
- ignore changes on status.

3. Don't update objectmeta (except finalizers) when status is updated.
**Release note**:
```release-note
CRDs support metadata.generation and implement spec/status split
```

- InstallHandler is the public interface through which all interaction
occurs.
- It is good to know whether the default ping is occurring to know due
to manual installation or automatic installation.
- It is good to know how many handlers are installed to see whether
code changes are taking effect.
- It is good to know the names of the handlers that are installed to
make sure that a handler a user thinks is installed is being
installed at runtime.
- Print all the checkers once

Remove incorrect patch-merge directives.
**What this PR does / why we need it**:
Directives were misplaced for the following types:
- MatchExpressions
- Taints
- Tolerations
Per the discussion in #46547, we cannot fix these because it would cause backwards-compatibility problems. Instead, remove the incorrect ones so they don't mislead users. This has no impact on behavior.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
