Implement equivalence cache by caching and re-using predicate result
The last part of #30844, I opened a new PR instead of overwrite the old one because we changed some basic assumption by allowing invalidating equivalence cache item by individual predicate.
The idea of this PR is based on discussion in https://github.com/kubernetes/kubernetes/issues/32024
- [x] Pods belong to same controllerRef considered to be equivalent
- [x] ` podFitsOnNode` will use cached predicate result if it's available
- [x] Equivalence cache will be updated when if a fresh new predicate is done
- [x] `factory.go` will invalid specific predicate cache(s) based on the object change
- [x] Since `schedule` and `bind` are async, we need to optimistically invalid affected cache(s) before `bind`
- [x] Fully unit test of affected files
- [x] e2e test to verify cache update/invalid workflow
- [x] performance test results
- [x] Some nits fixes related but expected to result in `needs-rebase` so they are split to: #36060#35968#37512

Remove affinity annotations leftover

**Special notes for your reviewer**:
- I remove the commented test cases and just leave TODOs instead. I think converting these untestable test cases for now is not necessary. We can add new test cases in future.
- I remove the e2e test case `validates that embedding the JSON PodAffinity and PodAntiAffinity setting as a string in the annotation value work` because we have a test case `validates that InterPod Affinity and AntiAffinity is respected if matching` to test the same thing.

Support customized system spec in the node conformance test and create the GKE system spec
ref: https://github.com/kubernetes/kubernetes/issues/46891
- System specs are located in `test/e2e_node/system/specs`. Created one for validating GKE images in `test/e2e_node/system/specs/gke.yaml`.
- `--image-spec-name` can be used to specify a system spec in node e2e and conformance tests. This option maps to `SYSTEM_SPEC_NAME` in a test properties file, which is the user facing configuration. So, users can specify `SYSTEM_SPEC_NAME=gke` to run the image validation using the GKE system spec.
- If `SYSTEM_SPEC_NAME` is unspecified, the default spec (`system.DefaultSysSpec`) will be used.
- We can also use `make test-e2e-node SYSTEM_SPEC_NAME=gke` to run tests using GKE image spec.

Azure PD (Managed/Blob)
This is exactly the same code as this [PR](https://github.com/kubernetes/kubernetes/pull/41950). It has a clean set of generated items. We created a separate PR to accelerate the accept/merge the PR
CC @colemickens
CC @brendandburns
**What this PR does / why we need it**:
1. Adds K8S support for Azure Managed Disks.
2. Adds support for dedicated blob disks (1:1 to storage account) in addition to shared blob disks (n:1 to storage account).
3. Automatically manages the underlying storage accounts. New storage accounts are created at 50% utilization. Max is 100 disks, 60 disks per storage account.
2. Addresses the current issues with Blob Disks:
..* Significantly faster attach process. Disks are now usually available for pods on nodes under 30 sec if formatted, under a min if not formatted.
..* Adds support to move disks between nodes.
..* Adds consistent attach/detach behavior, checks if the disk is leased/attached on a different node before attempting to attach to target nodes.
..* Fixes a random hang behavior on Azure VMs during mount/format (for both blob + managed disks).
..* Fixes a potential conflict by avoiding the use of disk names for mount paths. The new plugin uses hashed disk uri for mount path.
The existing AzureDisk is used as is. Additional "kind" property was added allowing the user to decide if the pd will be shared, dedicated or managed (Azure Managed Disks are used).
Due to the change in mounting paths, existing PDs need to be recreated as PV or PVCs on the new plugin.

LocalPV e2e test with two pods writing/reading to a shared file on one PVC
**What this PR does / why we need it**:
This PR adds an e2e test where one pod writes to a localPV and another reads from it. This e2e test is for the PersistentLocalVolumes alpha feature.
**Which issue this PR fixes**: fixes https://github.com/kubernetes/kubernetes/issues/48832
**Special notes for your reviewer**:
You need to setup the PersistentLocalVolumes feature-gate and NODE_LOCAL_SSDS environment variable.
For example:
```
KUBE_FEATURE_GATES="PersistentLocalVolumes=true" NODE_LOCAL_SSDS=1 go run hack/e2e.go -- -v --up
go run hack/e2e.go -- -v --test --test_args="--ginkgo.focus=\[Feature:LocalPersistentVolumes\]"
```
**Release note**:
```release-note
NONE
```
This PR fixes the following issues:
1. Use ResourceStorageScratch instead of ResourceStorage API to represent
local storage capacity
2. In eviction manager, use container manager instead of node provider
(kubelet) to retrieve the node capacity and reserved resources. Node
provider (kubelet) has a feature gate so that storagescratch information
may not be exposed if feature gate is not set. On the other hand,
container manager has all the capacity and allocatable resource
information.

Make storage e2e tests start with [sig-storage] instead of [k8s.io].
This makes understanding sig ownership from a test name very easy for

- Use a SIGDescribe helper function that adds a [sig-storage] prefix instead of [k8s.io] for tests in storage/
- Move a test that should be in storage into storage.
- Make tests owned by multiple SIGs (configmap test) have [sig-storage] instead of [Volume] labels.
This means that all tests that sig-storage directly owns can be found with a simple regex.

Fix some flakes in autoscaler e2e on gke
This PR should fix some of the flakes we found in e2e runs, while testing for 1.7 release:
- if one of the nodes is unschedulable in set up (causing set up to fail) we used to wait for wrong number of nodes in clean-up, adding unnecessary 20 minute wait to failing test
- we did not check for errors when creating RC in test, leading to tests failing later in hard to debug way (added retry loop and explicit test failure)

- Fix an issue that public IP resource not get deleted when switching from external loadbalancer to internal static loadbalancer.
**Special notes for your reviewer**:
1. Add new Azure resource tag to Public IP resources to indicate kubernetes managed resources.
Currently we determine whether the public IP resource should be deleted by looking at LoadBalancerIp property on spec. In the scenario 'Switching from external loadbalancer to internal loadbalancer with static IP', that value might have been updated for internal loadbalancer. So here we're to add an explicit tag for kubernetes managed resources.

Enable Node authorizer and NodeRestriction admission in kubemark

We want to ensure scale testing covers use of the authorizer/admission pair that partitions nodes. This includes enabling the authorizer, which populates a graph of existing nodes and pods.
Kubemark is still running all nodes with a single credential, so a follow-up step is to generate unique credentials per node (or enable TLS bootstrapping) and remove the temporary rolebinding added in this PR so the node authorizer is the one authorizing each call by a hollow node.

Shorten eviction tests, and increase test suite timeout
After #43590, the eviction manager is less aggressive when evicting pods. Because of that, many runs in the flaky suite time out.
To shorten the inode eviction test, I have lowered the eviction threshold.
To shorten the allocatable eviction test, I now set KubeReserved = NodeMemoryCapacity - 200Mb, so that any pod using 200Mb will be evicted. This shortens this test from 40 minutes, to 10 minutes.
While this should be enough to not hit the flaky suite timeout anymore, it is better to keep lower individual test timeouts than a lower suite timeout, since hitting the suite timeout means that even successful test runs are not reported.

Kubelet: rename cri package name to pkg/kubelet/apis/cri/v1alpha1/runtime
**What this PR does / why we need it**:
We have moved CRI from api/v1alpha1/runtime to apis/cri/v1alpha1, which changed the package name of CRI. This would cause a significant problem: old-versioned runtime (based on CRI in v1.6) doesn't work with latest kubelet v1.7, and vice versa.
This PR renames cri package name to `pkg/kubelet/apis/cri/v1alpha1/runtime` for fixing the problem.

Move the nvidia installer to the beginning.
When the installer runs for the first time, it disables loadpin and restarts
the node. So, it is better to run it in the beginning so that we can avoid
redoing the later steps. One of the later steps include downloading a tar file
and untarring it. Doing that only once saves around 1m30s in test runtime for
the gci image.

I'm getting close to the root cause: During tests, CreateGCEStaticIP() in fact successfully created static IP, but the parser we wrote in test mistakenly think we failed, probably because the gcloud output format was changed recently (or not). I'm still looking into fixing that.

Directly grab map values instead of using loop-clause variables when setting up federated sync controller tests.
Go's loop-clause variables are allocated once and the items are copied to that variable while iterating through the loop. This means, these variables can't escape the scope since closures are bound to loop-clause variables whose value change during each iteration. Doing so would lead to undesired behavior. For more on this topic see: https://github.com/golang/go/wiki/CommonMistakes

[GCE] Support internal load balancers
**What this PR does / why we need it**:
Allows users to expose K8s services externally of the K8s cluster but within their GCP network.
Fixes#33483
**Important User Notes:**
- This is a beta feature. ILB could be enabled differently in the future.
- Requires nodes having version 1.7.0+ (ILB requires health checking and a health check endpoint on kube-proxy has just been exposed)
- This cannot be used for intra-cluster communication. Do not call the load balancer IP from a K8s node/pod.
- There is no reservation system for private IPs. You can specify a RFC 1918 address in `loadBalancerIP` field, but it could be lost to another VM or LB if service settings are modified.
- If you're running an ingress, your existing loadbalancer backend service must be using BalancingMode type `RATE` - not `UTILIZATION`.
- Option 1: With a 1.5.8+ or 1.6.4+ version master, delete all your ingresses, and re-create them.
- Option 2: Migrate to a new cluster running 1.7.0. Considering ILB requires nodes with 1.7.0, this isn't a bad idea.
- Option 3: Possible migration opportunity, but use at your own risk. More to come later.

Handle failure cases on startup gracefully to avoid causing cascading
errors and poor initialization in other components. Initial errors from
config load cause the initializer to pause and hold requests. Return
typed errors to better communicate failures to clients.
Add code to handle two specific cases - admin wants to bypass
initialization defaulting, and mirror pods (which want to bypass
initialization because the kubelet owns their lifecycle).
This PR adds two features:
1. add support for isolating the emptyDir volume use. If user
sets a size limit for emptyDir volume, kubelet's eviction manager
monitors its usage
and evict the pod if the usage exceeds the limit.
2. add support for isolating the local storage for container overlay. If
the container's overly usage exceeds the limit defined in container
spec, eviction manager will evict the pod.
An annotation in the pod spec of the form:
podpreset.admission.kubernetes.io/exclude: "true"
Will cause the admission controller to skip manipulating the pod spec,
no matter the labelling.
The annotation for a podpreset acting on a pod has also been slightly
modified to contain a podpreset prefix:
podpreset.admission.kubernetes.io/podpreset-{name} = resource version

Fix AppArmor test for docker 1.13
... & better debugging.
The issue is that we run the pod containers in a shared PID namespace with docker 1.13, so PID 1 is no longer the container's root process. Since it's messy to get the container's root process, I switched to using `/proc/self` to read the apparmor profile. While this wouldn't catch a regression that caused only the init process to run with the wrong profile, I think it's a good approximation.

Add initializer support to admission and uninitialized filtering to rest storage
Initializers are the opposite of finalizers - they allow API clients to react to object creation and populate fields prior to other clients seeing them.
High level description:
1. Add `metadata.initializers` field to all objects
2. By default, filter objects with > 0 initializers from LIST and WATCH to preserve legacy client behavior (known as partially-initialized objects)
3. Add an admission controller that populates .initializer values per type, and denies mutation of initializers except by certain privilege levels (you must have the `initialize` verb on a resource)
4. Allow partially-initialized objects to be viewed via LIST and WATCH for initializer types
5. When creating objects, the object is "held" by the server until the initializers list is empty
6. Allow some creators to bypass initialization (set initializers to `[]`), or to have the result returned immediately when the object is created.
The code here should be backwards compatible for all clients because they do not see partially initialized objects unless they GET the resource directly. The watch cache makes checking for partially initialized objects cheap. Some reflectors may need to change to ask for partially-initialized objects.
```release-note
Kubernetes resources, when the `Initializers` admission controller is enabled, can be initialized (defaulting or other additive functions) by other agents in the system prior to those resources being visible to other clients. An initialized resource is not visible to clients unless they request (for get, list, or watch) to see uninitialized resources with the `?includeUninitialized=true` query parameter. Once the initializers have completed the resource is then visible. Clients must have the the ability to perform the `initialize` action on a resource in order to modify it prior to initialization being completed.

move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.
@kubernetes/sig-api-machinery-misc @kubernetes/api-reviewers @kubernetes/api-approvers
@derekwaynecarr since most of these are related to the kubelet
Add support for creating resources that are not immediately visible to
naive clients, but must first be initialized by one or more privileged
cluster agents. These controllers can mark the object as initialized,
allowing others to see them.
Permission to override initialization defaults or modify an initializing

[Flaky PR Test] Fix summary test
fixes issue: #46797
As we can see in the [example failure build log](https://storage.googleapis.com/kubernetes-jenkins/logs/ci-kubernetes-node-kubelet/4319/build-log.txt), the summary containers are pinging google 100s of times a second. This causes the summary container to be killed occasionally, and fail the test. The summary containers are only supposed to ping every 10 seconds according to the current test. As it turns out, we were missing a semicolon, and were not sleeping between pings. For background, we ping google to generate network traffic, so that the summary test can validate network metrics.
This PR adds the semicolon to make the container sleep between calls, and decreases the sleep time from 10 seconds to 1 second, as 1 call / 10 seconds did not produce enough activity.

Support validating package versions in node conformance test
**What this PR does / why we need it**:
This PR adds a package validator in node conformance test for checking whether the locally installed packages meet the image spec.
**Special notes for your reviewer**:
The image spec for GKE (which has the package spec) will be in a separate PR. Then we will publish a new node conformance test image for GKE whose name should use the convention in https://github.com/kubernetes/kubernetes/issues/45760 and have `gke` in it.

Respect PDBs during node upgrades and add test coverage to the
ServiceTest upgrade test. Modified that test so that we include pod
anti-affinity constraints and a PDB.
This PR adds the check for local storage request when admitting pods. If
the local storage request exceeds the available resource, pod will be
rejected.
This PR adds the support for allocatable local storage (scratch space).
This feature is only for root file system which is shared by kubernetes
componenets, users' containers and/or images. User could use
--kube-reserved flag to reserve the storage for kube system components.
If the allocatable storage for user's pods is used up, some pods will be
evicted to free the storage resource.

Add TPR to CRD migration helper.
This is a helper for migrating TPR data to CustomResource. It's rather hacky because it requires crossing apiserver boundaries, but doing it this way keeps the mess contained to the TPR code, which is scheduled for deletion anyway.
It's also not completely hands-free because making it resilient enough to be completely automated is too involved to be worth it for an alpha-to-beta migration, and would require investing significant effort to fix up soon-to-be-deleted TPR code. Instead, this feature will be documented as a best-effort helper whose results should be verified by hand.
The intended benefit of this over a totally manual process is that it should be possible to copy TPR data into a CRD without having to tear everything down in the middle. The process would look like this:
1. Upgrade to k8s 1.7. Nothing happens to your TPRs.
1. Create CRD with group/version and resource names that match the TPR. Still nothing happens to your TPRs, as the CRD is hidden by the overlapping TPR.
1. Delete the TPR. The TPR data is converted to CustomResource data, and the CRD begins serving at the same REST path.
Note that the old TPR data is left behind by this process, so watchers should not receive DELETE events. This also means the user can revert to the pre-migration state by recreating the TPR definition.

Node authorizer
This PR implements the authorization portion of https://github.com/kubernetes/community/blob/master/contributors/design-proposals/kubelet-authorizer.md and kubernetes/features#279:
* Adds a new authorization mode (`Node`) that authorizes requests from nodes based on a graph of related pods,secrets,configmaps,pvcs, and pvs:
* Watches pods, adds edges (secret -> pod, configmap -> pod, pvc -> pod, pod -> node)
* Watches pvs, adds edges (secret -> pv, pv -> pvc)
* When both Node and RBAC authorization modes are enabled, the default RBAC binding that grants the `system:node` role to the `system:nodes` group is not automatically created.
* Tightens the `NodeRestriction` admission plugin to require identifiable nodes for requests from users in the `system:nodes` group.
This authorization mode is intended to be used in combination with the `NodeRestriction` admission plugin, which limits the pods and nodes a node may modify. To enable in combination with RBAC authorization and the NodeRestriction admission plugin:
* start the API server with `--authorization-mode=Node,RBAC --admission-control=...,NodeRestriction,...`
* start kubelets with TLS boostrapping or with client credentials that place them in the `system:nodes` group with a username of `system:node:<nodeName>`
```release-note
kube-apiserver: a new authorization mode (`--authorization-mode=Node`) authorizes nodes to access secrets, configmaps, persistent volume claims and persistent volumes related to their pods.
* Nodes must use client credentials that place them in the `system:nodes` group with a username of `system:node:<nodeName>` in order to be authorized by the node authorizer (the credentials obtained by the kubelet via TLS bootstrapping satisfy these requirements)
* When used in combination with the `RBAC` authorization mode (`--authorization-mode=Node,RBAC`), the `system:node` role is no longer automatically granted to the `system:nodes` group.
```
```release-note
RBAC: the automatic binding of the `system:node` role to the `system:nodes` group is deprecated and will not be created in future releases. It is recommended that nodes be authorized using the new `Node` authorization mode instead. Installations that wish to continue giving all members of the `system:nodes` group the `system:node` role (which grants broad read access, including all secrets and configmaps) must create an installation-specific ClusterRoleBinding.
```
Follow-up:
- [ ] enable e2e CI environment with admission and authorizer enabled (blocked by kubelet TLS bootstrapping enablement in https://github.com/kubernetes/kubernetes/pull/40760)
- [ ] optionally enable this authorizer and admission plugin in kubeadm
- [ ] optionally enable this authorizer and admission plugin in kube-up

Support grabbing test suite metrics

Add support for grabbing metrics that cover the entire test suite's execution.
Update the "interesting" controller-manager metrics to match the

GCE - Refactor API for firewall and backend service creation
**What this PR does / why we need it**:
- Currently, firewall creation function actually instantiates the firewall object; this is inconsistent with the rest of GCE api calls. The API normally gets passed in an existing object.
- Necessary information for firewall creation, (`computeHostTags`,`nodeTags`,`networkURL`,`subnetworkURL`,`region`) were private to within the package. These now have public getters.
- Consumers might need to know whether the cluster is running on a cross-project network. A new `OnXPN` func will make that information available.
- Backend services for regions have been added. Global ones have been renamed to specify global.
- NamedPort management of instance groups has been changed from an `AddPortsToInstanceGroup` func (and missing complementary `Remove...`) to a single, simple `SetNamedPortsOfInstanceGroup`
- Addressed nitpick review comments of #45524
ILB needs the regional backend services and firewall refactor. The ingress controller needs the new `OnXPN` func to decide whether to create a firewall.

Move NetworkPolicy to v1
Move NetworkPolicy to v1
@kubernetes/sig-network-misc
**Release note**:
```release-note
NetworkPolicy has been moved from `extensions/v1beta1` to the new
`networking.k8s.io/v1` API group. The structure remains unchanged from
the beta1 API.
The `net.beta.kubernetes.io/network-policy` annotation on Namespaces
to opt in to isolation has been removed. Instead, isolation is now
determined at a per-pod level, with pods being isolated if there is
any NetworkPolicy whose spec.podSelector targets them. Pods that are
targeted by NetworkPolicies accept traffic that is accepted by any of
the NetworkPolicies (and nothing else), and pods that are not targeted
by any NetworkPolicy accept all traffic by default.
Action Required:
When upgrading to Kubernetes 1.7 (and a network plugin that supports
the new NetworkPolicy v1 semantics), to ensure full behavioral
compatibility with v1beta1:
1. In Namespaces that previously had the "DefaultDeny" annotation,
you can create equivalent v1 semantics by creating a
NetworkPolicy that matches all pods but does not allow any
traffic:
kind: NetworkPolicy
apiVersion: networking.k8s.io/v1
metadata:
name: default-deny
spec:
podSelector:
This will ensure that pods that aren't match by any other
NetworkPolicy will continue to be fully-isolated, as they were
before.
2. In Namespaces that previously did not have the "DefaultDeny"
annotation, you should delete any existing NetworkPolicy
objects. These would have had no effect before, but with v1
semantics they might cause some traffic to be blocked that you
didn't intend to be blocked.

Detect cohabitating resources in etcd storage test
**What this PR does / why we need it**:
This change updates the etcd storage path test to detect cohabitating resources by looking at their expected location in etcd. This was not detected in the past because the GVK check did not span across groups.
To limit noise from failures caused by multiple objects at the same location in etcd, the test now fails when different GVRs share the same expected path. Thus every object is expected to have a unique path.

Enable "kick the tires" support for Nvidia GPUs in COS
This PR provides an installation daemonset that will install Nvidia CUDA drivers on Google Container Optimized OS (COS).
User space libraries and debug utilities from the Nvidia driver installation are made available on the host in a special directory on the host -
* `/home/kubernetes/bin/nvidia/lib` for libraries
* `/home/kubernetes/bin/nvidia/bin` for debug utilities
Containers that run CUDA applications on COS are expected to consume the libraries and debug utilities (if necessary) from the host directories using `HostPath` volumes.
Note: This solution requires updating Pod Spec across distros. This is a known issue and will be addressed in the future. Until then CUDA workloads will not be portable.
This PR updates the COS base image version to m59. This is coupled with this PR for the following reasons:
1. Driver installation requires disabling a kernel feature in COS.
2. The kernel API for disabling this interface changed across COS versions
3. If the COS image update is not handled in this PR, then a subsequent COS image update will break GPU integration and will require an update to the installation scripts in this PR.
4. Instead of having to post `3` PRs, one each for adding the basic installer, updating COS to m59, and then updating the installer again, this PR combines all the changes to reduce review overhead and latency, and additional noise that will be created when GPU tests break.

1. Get Quota for GPUs in any region
2. `export `KUBE_GCE_ZONE=<zone-with-gpus>` KUBE_NODE_OS_DISTRIBUTION=gci`
3. `NODE_ACCELERATORS="type=nvidia-tesla-k80,count=1" cluster/kube-up.sh`
4. `kubectl create -f cluster/gce/gci/nvidia-gpus/cos-installer-daemonset.yaml`
5. Run your CUDA app in a pod.
**Another option is to run a e2e manually to try out this PR**
1. Get Quota for GPUs in any region
2. export `KUBE_GCE_ZONE=<zone-with-gpus>` KUBE_NODE_OS_DISTRIBUTION=gci
3. `NODE_ACCELERATORS="type=nvidia-tesla-k80,count=1"`
4. `go run hack/e2e.go -- --up`
5. `hack/ginkgo-e2e.sh --ginkgo.focus="\[Feature:GPU\]"`
The e2e will install the drivers automatically using the daemonset and then run test workloads to validate driver integration.
TODO:
- [x] Update COS image version to m59 release.
- [x] Remove sleep from the install script and add it to the daemonset
- [x] Add an e2e that will run the daemonset and run a sample CUDA app on COS clusters.
- [x] Setup a test project with necessary quota to run GPU tests against HEAD to start with https://github.com/kubernetes/test-infra/pull/2759
- [x] Update node e2e serial configs to install nvidia drivers on COS by default

Scheduler should use a shared informer, and fix broken watch behavior for cached watches
Can be used either from a true shared informer or a local shared
informer created just for the scheduler.
Fixes a bug in the cache watcher where we were returning the "current" object from a watch event, not the historic event. This means that we broke behavior when introducing the watch cache. This may have API implications for filtering watch consumers - but on the other hand, it prevents clients filtering from seeing objects outside of their watch correctly, which can lead to other subtle bugs.
```release-note
The behavior of some watch calls to the server when filtering on fields was incorrect. If watching objects with a filter, when an update was made that no longer matched the filter a DELETE event was correctly sent. However, the object that was returned by that delete was not the (correct) version before the update, but instead, the newer version. That meant the new object was not matched by the filter. This was a regression from behavior between cached watches on the server side and uncached watches, and thus broke downstream API clients.

Support parallel scaling on StatefulSets
Fixes#41255
```release-note
StatefulSets now include an alpha scaling feature accessible by setting the `spec.podManagementPolicy` field to `Parallel`. The controller will not wait for pods to be ready before adding the other pods, and will replace deleted pods as needed. Since parallel scaling creates pods out of order, you cannot depend on predictable membership changes within your set.

Make CPU request for heapster in kubemark scale with the number of Nodes
This change updates the etcd storage path test to detect cohabitating
resources by looking at their expected location in etcd. This was not
detected in the past because the GVK check did not span across groups.
To limit noise from failures caused by multiple objects at the same
location in etcd, the test now fails when different GVRs share the same
expected path. Thus every object is expected to have a unique path.

Previously, the scheduler created two separate list watchers. This
changes the scheduler to be able to leverage a shared informer, whether
passed in externally or spawned using the new in place method. This
removes the last use of a "special" informer in the codebase.
Allows someone wrapping the scheduler to use a shared informer if they
have more information avaliable.
Tokens controller previously needed a bit of extra help in order to be
safe for concurrent use. The new MutationCache allows it to keep a local
cache and still use a shared informer. The filtering event handler lets
it only see changes to secrets it cares about.

Command tree and exported env in kubectl plugins
This is part of `kubectl` plugins V1:
- Adds support to several env vars passing context information to the plugin. Plugins can make use of them to connect to the REST API, access global flags, get the path of the plugin caller (so that `kubectl` can be invoked) and so on. Exported env vars include
- `KUBECTL_PLUGINS_DESCRIPTOR_*`: the plugin descriptor fields
- `KUBECTL_PLUGINS_GLOBAL_FLAG_*`: one for each global flag, useful to access namespace, context, etc
- ~`KUBECTL_PLUGINS_REST_CLIENT_CONFIG_*`: one for most fields in `rest.Config` so that a REST client can be built.~
- `KUBECTL_PLUGINS_CALLER`: path to `kubectl`
- `KUBECTL_PLUGINS_CURRENT_NAMESPACE`: namespace in use
- Adds support for plugins as child of other plugins so that a tree of commands can be built (e.g. `kubectl myplugin list`, `kubectl myplugin add`, etc)
**Release note**:
```release-note
Added support to a hierarchy of kubectl plugins (a tree of plugins as children of other plugins).
Added exported env vars to kubectl plugins so that plugin developers have access to global flags, namespace, the plugin descriptor and the full path to the caller binary.

Log age of stats used for evictions during eviction tests
I recently added prometheus metrics for the age of the metrics used for evictions #43031. It would be nice to surface these during eviction tests, so I can better assess how old stats are, and whether or not the age of stats causes extra evictions.
This isnt super-high priority, and can be done after code-freeze, since it is a testing improvement. Feel free to take a look whenever either of you has time.

ResourceQuota admission control injects registry
**What this PR does / why we need it**:
The `ResourceQuota` admission controller works with a registry that maps a GroupKind to an Evaluator. The registry used in the existing plug-in is not injectable, which makes usage of the ResourceQuota plug-in in other API server contexts difficult. This PR updates the code to support late injection of the registry via a plug-in initializer.
