API changes for Cascading deletion
This PR includes the necessary API changes to implement cascading deletion with finalizers as proposed is in #23656. Comments are welcome.
@lavalamp @derekwaynecarr @bgrant0607 @rata @hongchaodeng
The codec factory should support two distinct interfaces - negotiating
for a serializer with a client, vs reading or writing data to a storage
form (etcd, disk, etc). Make the EncodeForVersion and DecodeToVersion
methods only take Encoder and Decoder, and slight refactoring elsewhere.
In the storage factory, use a content type to control what serializer to
pick, and use the universal deserializer. This ensures that storage can
read JSON (which might be from older objects) while only writing
protobuf. Add exceptions for those resources that may not be able to
write to protobuf (specifically third party resources, but potentially
others in the future).

Petset controller
Took longer than I expected. Main parts of this pr are:
1. Identity generation based on petset spec (volumes are mapped per discussion in #18016)
2. Ensure that we create/delete pets in sequence
3. Ensuring that we create, wait for healthy, create; or delete, wait for terminationGrace, delete
4. Controller that watches apiserver and drives actual -> desired
PVCs are not deleted, yet.

Deleting duplicate code from federated-apiserver.Run()
This removes most of duplicate code from federated-apiserver.Run().
The code remaining is related to storage or authz and authn.
https://github.com/kubernetes/kubernetes/pull/24787 refactors the storage related code.
I am still figuring out authz and authn.

Provide flags to use etcd3 backed storage
ref: #24405
What's in this PR?
- Add a new flag "storage-backend" to choose "etcd2" or "etcd3". By default (i.e. empty), it's "etcd2".
- Take out etcd config code into a standalone package and let it create etcd2 or etcd3 storage backend given user input.

Generated clients can return their RESTClients, RESTClient can return its RateLimiter

Add kubelet flags for eviction threshold configuration
This PR just adds the flags for kubelet eviction and the associated generated code.
I am happy to tweak text, but we can also do that later at this point in the release.
Since this causes codegen, I wanted to stage this first.

update controllers watching all pods to share an informer
This plumbs the shared pod informer through the various controllers to avoid duplicated watches.

All clients under ClientSet share one RateLimiter.
Currently we create a rate limiter for each client in client set. It makes the reasoning about rate limiting behavior much harder. This PR changes this behavior and now all clients in the set share single rate limiter. Ref. #24157

Make fake client actions use fully qualified resource
The output of a versioned clientset is version object. The fake client used to assume only internal objects will be returned. This PR removes this assumption by making fake actions initialized with a fully qualified resource instead of a resource string.
We have to regenerate fake clients in release_1_2 clientset to let it compile. For the test fakes, we are breaking the backwards compatibility promise.
Part of #24155.

client-gen: use serializer instead of codec for versioned client
For a versioned client, because the output of every client method is a versioned object, so it should use a serializer instead of a codec that does conversion.

genericapiserver: Moving more flags to ServerRunOptions
Moving more apiserver flags to generic api server.
With this change, most of the Config is created in genericapiserver.NewConfig(). The plan is to move everything there.
I didnt touch Storage related params as they are being changed in https://github.com/kubernetes/kubernetes/pull/23208.
And I will handle authz and authn in another PR (need to figure out a few things).
