Move the namespace selector code to package webhook/namespace
Move the conversion related code to package to webhook/versioned
Move errors related code to package webhook/errors
Move admission review related code to package webhook/request
Kubernetes-commit: 51774697b35314b078270e9da24fbe0ff843b981
Scheme conversion should support unstructured conversion natively to
allow going from unstructured to typed and back. It is not a higher
level responsibility to do that conversion because the scheme is the
only one who knows what types it supports.

Add MutatingWebhookConfiguration type
As part of Mutating Webhook support, this PR adds the configuration for Mutating webhooks. It also renames existing ReadOnly webhook configurations from ExternalAdmissionHookConfiguration to ValidatingWebhookConfiguration. As part of the process some sub-types are also renamed.
Lastly, the mutating webhook configurations are sorted by name to make the serial executing of them deterministic.

Move core API to pkg/apis/core
Fixes https://github.com/kubernetes/kubernetes/issues/55304.
This moves the types in pkg/api and most of pkg/api/v1 to pkg/apis/core to match the other api groups, following-up on what https://github.com/kubernetes/kubernetes/pull/44784 did for the external types.
It's a nearly 100% mechanical package move with a number of trivial fixups in code-generators and in tests which do string comparisons of types via reflection.
**Most importantly:**
- group names are unchanged
- apimachinery semantics are unchanged
- the outside api is unchanged.
Note that some packages for helpers are left in pkg/api/v1. Splitting them into helpers which belong tightly to the api and those which are not is left to follow-ups.

When I'm working on PR: https://github.com/kubernetes/kubernetes/pull/54782, I met a problem here: https://github.com/golang/protobuf/issues/372, which I think we need to update our vendor of protobuf
and I ask Dr. Stefan for suggestion, here is our coversation
shiywang [5:09 PM]
hi, Dr. Stefan i'm sorry to bother, I have a simple question, I was working on a pr which need to use protobuf custom field, and I run into this problem here: https://github.com/golang/protobuf/issues/372 which I think is due to our codebase's protobuf vendor is too old `vendor/github.com/golang/protobuf`, do you think I can update that vendor to lastest one ? also I noticed there's also an extend package called `vendor/github.com/gogo/protobuf/proto` what's the releationship between those two ? which one should I update ?
