Allow anonymous API server access, decorate authenticated users with system:authenticated group
When writing authorization policy, it is often necessary to allow certain actions to any authenticated user. For example, creating a service or configmap, and granting read access to all users
It is also frequently necessary to allow actions to any unauthenticated user. For example, fetching discovery APIs might be part of an authentication process, and therefore need to be able to be read without access to authentication credentials.
This PR:
* Adds an option to allow anonymous requests to the secured API port. If enabled, requests to the secure port that are not rejected by other configured authentication methods are treated as anonymous requests, and given a username of `system:anonymous` and a group of `system:unauthenticated`. Note: this should only be used with an `--authorization-mode` other than `AlwaysAllow`
* Decorates user.Info returned from configured authenticators with the group `system:authenticated`.
This is related to defining a default set of roles and bindings for RBAC (https://github.com/kubernetes/features/issues/2). The bootstrap policy should allow all users (anonymous or authenticated) to request the discovery APIs.
```release-note
kube-apiserver learned the '--anonymous-auth' flag, which defaults to true. When enabled, requests to the secure port that are not rejected by other configured authentication methods are treated as anonymous requests, and given a username of 'system:anonymous' and a group of 'system:unauthenticated'.
Authenticated users are decorated with a 'system:authenticated' group.
NOTE: anonymous access is enabled by default. If you rely on authentication alone to authorize access, change to use an authorization mode other than AlwaysAllow, or or set '--anonymous-auth=false'.

Copy auth plugin to client-go repo
client-go doesn't copy the [auth plugin](https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/client/auth/plugins.go). This causes user cannot access cluster run by GKE. User will see error "No Auth Provider found for name gcp".
This PR fixes this issue. It's marked as WIP because I'll need to rebase after #32906 gets merged. Also, the fix needs to be cherry-picked into 1.4 branch to update client-go/1.4.
Previously we refused to emit 'autoConvert_*' functions if any field was not
convertible. The way around this was to write manual Conversion functions, but
to do so safely you must handle every fields. Huge opportunity for errors.
This PR cleans up the filtering such that it only operates on types that should
be converted (remove a lot of code) and tracks when fields are skipped. In
that case, it emits an 'autoConvert' function but not a public 'Convert'
function. If there is no manual function, the compile will fail.
This also means that manual conversion functions can call autoConvert functions
and then "patch up" what they need.

**What this PR does / why we need it**: Fixes a memory leak
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#33186
**Special notes for your reviewer**: Every second new goroutines are created and are getting blocked waiting for the lock in the event queue. only one worker will get a lock when there are some events to process, so all the goroutines which are created every second waits for the lock forever and causes the memory/goroutine leak.
As a fix the new worker will be created only when there is no worker exist. and only one worker per cluster either waits for the event or processes all the events and goes out of existence.
```release-note
Fixes memory/goroutine leak in Federation Service controller.

remove storage related fields from genericapiserver
Removes `StorageFactory` and `StorageDecorator` from from `genericapiserver` since both constructs are related to building a `RESTStorage`, which should be provided fully formed (or via factory func) to a truly generic API server.
I found this while trying to move the creation API routes earlier.

Correct versioned.Event output in Swagger
Fixes#24240
```release-note
The value of the `versioned.Event` object (returned by watch APIs) in the Swagger 1.2 schemas has been updated from `*versioned.Event` which was not expected by many client tools. The new value is consistent with other structs returned by the API.

move registry packages for all API groups
This continues the pattern of `registry/<group>/resource` for our backing storage. This entire pull is nothing but moves. I'll reswizzle the actual storage next, but these are cargo-culted everywhere, so I want to lay this down early.

Allow secure access to apiserver from Admission Controllers
* Allow options.InsecurePort to be set to 0 to switch off insecure access
* In NewSelfClient, Set the TLSClientConfig to the cert and key files
if InsecurePort is switched off
* Mint a bearer token that allows the client(s) created in NewSelfClient
to talk to the api server
* Add a new authenticator that checks for this specific bearer token

Move generated openAPI specs out of genericapiserver and make it configurable
A follow up to #31468
Generated OpenAPI Spec does not belong to genericapiserver package. A new package "generated" created in hope of all generated codes goes into it in future. Openapi folder of that package contains generated definitions and generic API server will accept the definition map as a configuration parameter.
Reference: #13414
* Allow options.InsecurePort to be set to 0 to switch off insecure access
* In NewSelfClient, Set the TLSClientConfig to the cert and key files
if InsecurePort is switched off
* Mint a bearer token that allows the client(s) created in NewSelfClient
to talk to the api server
* Add a new authenticator that checks for this specific bearer token

Cleanup non-rest apiserver handlers
- rename MuxHelper -> PathRecorderMux
- move non-rest handlers into routes packages within genericapiserver and `pkg/routes` (those from master)
- move ui and logs handlers out of genericapiserver (they are
not generic)
- make version handler configurable (`config.EnableVersion`)
