operator: add register-gen and conversion-gen

Adds the following binaries to our nix shell:
- `conversion-gen` (unused)
- `defaulter-gen` (unused)
- `register-gen`

Existing CRD packages have been refactored to rely on `register-gen` to
generate `SchemaBuilder` and call `Register` on root object types.

The majority of changes are rote; either changing AddToScheme -> Install,
removal of modifications to k8s' global schema, or generated code differences.
