API for server side tabular output
These are the APIs necessary to implement propsoal kubernetes/community#363
They consist of a new meta group (v1alpha1) that indicates these are alpha apis for the server as a whole, a new kind `TableList` which is a simple row + header arranged table capable of returning both object and columnar data, a `TableListOptions` for altering the behavior of the return, and `PartialObjectMetadata` which is an "interface" style API object which allows a client to ask any object for their metadata (without having to know how to parse the object or perform gymnastics).
Extracted from #40848
A few minor tweaks still required.

start serving customresourcedefinition based on status
This exposes the `customresourcedefinition/status` endpoint, wires a controller to drive `NameConflict` conditions, and serves discovery from status, not spec.
Next steps after this include wiring the conditions into handling and reswizzling the handling chain to be cleaner now that we have a custom mux.

Ensure ordering of using dynamic kubelet config and setting up tests.
This PR simply places the body of the eviction test within its own context. This ensures that the kubelet config is set before the pods are created, and that the kubelet config is reverted only after the pods are deleted.

[Federation] Segregate DNS related code to separate controller
**What this PR does / why we need it**:
This is the continuation of service controller re-factor work as outlined in #41253
This PR segregates DNS related code from service controller to another controller `service-dns controller` which manages the DNS records on the configured DNS provider.
`service-dns controller` monitors the federated services for the ingress annotations and create/update/delete DNS records accordingly.
`service-dns controller` can be optionally disabled and DNS record management could be done by third party components by monitoring the ingress annotations on federated services. (This would enable something like federation middleware for CoreDNS where federation api server could be used as a backend to CoreDNS eliminating the need for etcd storage.)
**Special notes for your reviewer**:
**Release note**:
```
Federation: A new controller for managing DNS records is introduced which can be optionally disabled to enable third party components to manage DNS records for federated services.
```

kubectl plugin: Expand environment variables in the command of plugin.yaml
**What this PR does / why we need it**:
This commit improves kubectl plugins to expand environment variables in the command of plugin.yaml.

The hello plugin is a new
plugin used by test-cmd
to test multiple plugin locations.

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.
```

Update 'More info' links on API types and fields
> **Please just review the first commit, the rest is generated files.**
Recent docs website shuffling during 1.6 caused majority of links in the API
types and fields to break. Since we do not have server-side 301 redirects, user
has to click an extra link, and the #target fragment in the URL will be lost. (This is
because GitHub’s redirect_from feature is not ideal.)
For the time being, I have manually gone through all of them to bring them up to date
and add HTTPS to those missing it. This is a docs-only change and impacts generated
code, generated swaggers, API reference docs etc.
cc: @steveperry-53 @devin-donnelly @chenopis fyi, docs links changes (even small title changes) easily breaks links in API reference, Swagger, kubectl explain, and many other places.

Fix attach volume to instance repeatedly
1.When volume's status is 'attaching', controllermanager will attach
it again and return err. So it is necessary to check volume's
status before attach/detach volume.
2. When volume's status is 'attaching', its attachments will be None,
controllermanager can't get device path and make some failed event.
But it is normal, so don't return err when attachments is None

Make createEndpointService() and deleteEndpointService() plugin interface methods.
Why this change?
In some setups, after creation of dynamic PVs and before mounting/using these PVs in a pod, the endpoint/service got mistakenly deleted by the user/developer. By making these methods 'plugin' specific, we can call it from mounter if there are scenarios where the endpoint and service got wiped in between accidentally.
