OpenApi Code generation using other tool

[Jolanrensen]

Found this interesting library for Kotlin/Java code generation from OpenApi schemas. While we already have support, there are still some issues with the code generation (https://github.com/Kotlin/dataframe/issues?q=is%3Aopen+is%3Aissue+label%3AOpenAPI) that need some attention.

I want to take a look at this library, however, to see if it could replace some of the instable behavior of our OpenApi generation. Probably our implementation works well enough to keep, but at least it should be explored.

Hurdy-Gurdy

OpenApi Generator is another interesting tool for which I made an example project that combines the compiler plugin and this generator: https://github.com/Jolanrensen/df-openapi-generator-plugin-demo. It has promise! Especially in notebooks and with the compiler plugin.
