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.

A daemonset deployment is included to make it easy to consume the installer
A cluster e2e has been added to test the installation daemonset along with verifying installation
by using a sample CUDA application.
Node e2e for GPUs updated to avoid running on nodes without GPU devices.

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.

Remove the deprecated --babysit-daemons kubelet flag
```release-note
Removes the deprecated kubelet flag --babysit-daemons
```
This flag has been deprecated for over a year (git blame says marked deprecated on March 1, 2016).
Relatively easy removal - nothing in the Kubelet relies on it anymore.
There was still some stuff in the provisioning scripts. It was easy to rip out, but in general we probably need to be more disciplined about updating the provisioning scripts at the same time that we initially mark things deprecated.

Apiregistration v1alpha1→v1beta1
Promoting apiregistration api from v1alpha1 to v1beta1.
API Registration is responsible for registering an API `Group`/`Version` with
another kubernetes like API server. The `APIService` holds information
about the other API server in `APIServiceSpec` type as well as general
`TypeMeta` and `ObjectMeta`. The `APIServiceSpec` type have the main
configuration needed to do the aggregation. Any request coming for
specified `Group`/`Version` will be directed to the service defined by
`ServiceReference` (on port 443) after validating the target using provided
`CABundle` or skipping validation if development flag `InsecureSkipTLSVerify`
is set. `Priority` is controlling the order of this API group in the overall
discovery document.
The return status is a set of conditions for this aggregation. Currently
there is only one condition named "Available", if true, it means the
api/server requests will be redirected to specified API server.
```release-note
API Registration is now in beta.

Reorganize kubelet tree so apis can be independently versioned
@yujuhong @lavalamp @thockin @bgrant0607
This is an example of how we might reorganize `pkg/kubelet` so the apis it exposes can be independently versioned. This would also provide a logical place to put the `KubeletConfiguration` type, which currently lives in `pkg/apis/componentconfig`; it could live in e.g. `pkg/kubelet/apis/config` instead.
Take a look when you have a chance and let me know what you think. The most significant change in this PR is reorganizing `pkg/kubelet/api` to `pkg/kubelet/apis`, the rest is pretty much updating import paths and `BUILD` files.

Promotes Source IP preservation for Virtual IPs from Beta to GA
Fixes#33625. Feature issue: kubernetes/features#27.
Bullet points:
- Declare 2 fields (ExternalTraffic and HealthCheckNodePort) that mirror the ESIPP annotations.
- ESIPP alpha annotations will be ignored.
- Existing ESIPP beta annotations will still be fully supported.
- Allow promoting beta annotations to first class fields or reversely.
- Disallow setting invalid ExternalTraffic and HealthCheckNodePort on services. Default ExternalTraffic field for nodePort or loadBalancer type service to "Global" if not set.
**Release note**:
```release-note
Promotes Source IP preservation for Virtual IPs to GA.
Two api fields are defined correspondingly:
- Service.Spec.ExternalTrafficPolicy <- 'service.beta.kubernetes.io/external-traffic' annotation.
- Service.Spec.HealthCheckNodePort <- 'service.beta.kubernetes.io/healthcheck-nodeport' annotation.

Remove a test utility function that is redundant and kinda broken
Framework.WaitForAnEndpoint() has no timeout, so if something goes wrong and the endpoint doesn't get created, the test will hang forever. (This is happening for some reason sometimes in OpenShift right now, and when the CI system eventually times out and kills the VM, it loses the logs that would explain what failed.)
There's already another nearly-identical WaitForEndpoint() method that *does* take a timeout, so people can just use that instead.

Fix flag formatting errors in the node tests
There were three problems:
- Lack of a trailing space after prepending flags.
- Passing multiple flags in a string to --kubelet-flags seems to confuse
the flag parser; it stops parsing ALL flags as soon as it sees the
second kubelet flag. Fortunately, all instances of --kubelet-flags are
combined together, so we can just pass two of those.
- --feature-gates should be passed to the test framework, which then
forwards it to the kubelet, instead of using --kubelet-flags.
This hopefully fixes the dynamic config test failures on COS, which
started after #45602. (See: https://k8s-testgrid.appspot.com/google-node#kubelet-serial-gce-e2e)
