OpenAPI generator errors out with Redfish schema

I think for Go, we can at least guide the group to add support for the enumClassPrefix option for server builds. It seems like others have been able to get Redfish to work with Go clients with that option (as well as other massaging of the existing schemas like we're trying to do at the moment).

I'm going to file an issue in the OpenAPI Generator project to add support for enumClassPrefix for Go server.
