openapi-gen lacks support for enum

[nikhita]

From @tamalsaha's issue kubernetes/kubernetes#62325 and @mbohlool's suggestion to open an issue in this repo (kubernetes/kubernetes#62325 (comment)),

Currently I generate CRD schema validation using a pipeline like below:

types.go ---(openapi-gen) ---> openapi_generated.go ---(crd-validation)---> crd.yaml

While this works, openapi-gen does not generate spec information for enums . We would like to see this supported.
