[ISSUE #168] Upload auto generated files for third-party reference

[drivebyer]

for example:

• https://github.com/istio/istio/tree/master/operator/pkg/apis/istio/v1alpha1
• https://github.com/minio/operator/tree/master/pkg/apis/minio.min.io/v2
• https://github.com/grafana-operator/grafana-operator/tree/master/api/v1beta1
• https://github.com/cockroachdb/cockroach-operator/tree/master/apis/v1alpha1
• ...

I think we should follow the convention
