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).

YAML is not guaranteed to be recognizable, so we need to bump JSON and
protobuf above it in the decoding order. Add a unit test.

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.
