Define yaml configuration structure as WIDL?

[jsoverson]

I was looking to create a JSON schema for the configuration files and it would be easy to do if it was defined as WIDL. That way it could be used to codegen the go code, the JSON schema, and documentation while also being a good example for how to use WIDL for use cases outside of waPC guests.

The WIDL is straightforward outside of the config object (code). I'm not sure how to best describe that with the current state of WIDL but @pkedy you would know best.

type WapcConfig {
  schema: string,
  config: {string: any},
  generates: {string: Target}
}

type Target {
  module: string,
  visitorClass: string,
  ifNotExists: boolean,
  config: {string: any}
}
