Add a new API version apps/v1beta2

xref: #49135
This PR adds a new API version `apps/v1beta2` which contains a copy (of types, conversions, and defaults) of `apps/v1beta1` StatefulSet, Deployment, and their subresources. Note that `apps/v1beta2` is still WIP and we will make breaking changes to it before releasing 1.8.

Moving core controllers (StatefulSet, Deployment, ReplicaSet, DaemonSet) to `apps/v1beta2` is the first step of moving them to `apps/v1` (GA). 

This PR is a starting point for DaemonSet and ReplicaSet to move from `/extensions` to `/apps` and for Deployment and StatefulSet to make some breaking changes (e.g. new defaults and/or remove deprecated fields).
