Integrate with OpenAPI Javascript client generator

[ia3andy]

It would be nice to integrate with some OpenAPI Javascript client generator. It would automatically generate the client for the Quarkus OpenAPI.

I am not sure how this could fit in the Quinoa flow yet. Generating at build time would mean no auto-completion & IDE showing errors.

We could use:

• https://github.com/swagger-api/swagger-codegen
• https://github.com/OpenAPITools/openapi-generator-cli

I tested both and the generated code is super-heavy.

Also an alternative is to use https://www.npmjs.com/package/swagger-client on /q/openapi since they backend/frontend are on the same server. I am not a fan of the syntax et verbosity of the calls though.
