Creating a new API group is really hard. I'll keep this description up to date as I go through the pain.

1. You have to know to add yourself to the import_known_versions.go files in multiple packages to get included.
2. You have to manually update these files to get the generated output:
   1. hack/after-build/update-generated-conversions.sh
   2. hack/after-build/update-generated-deep-copies.sh
   3. hack/after-build/verify-generated-conversions.sh
   4. hack/after-build/verify-generated-deep-copies.sh
   5. hack/update-generated-swagger-docs.sh
3. You have to manually create types.generated.go in every internal and external package to get codec-gen to work.
4. You have to update pkg/api/registered/registered.go to be allowed to install your group.

That's just to get your types registered. Right now, there's no pluggable way to include custom RESTStorage into the API server for my new types.
