This commit introduces the Validator interface, which is intended to be implemented by any sub configs. It specifies a Validate() error method that should fail if a sub configuration contains any invalid or insane parameters. In addition, a package-level Validate method can be used to check a variadic number of sub configs implementing the Validator interface. This allows the primary config struct to be extended via targeted and/or specialized sub configs, and validate all of them in sequence without bloating the main package with the actual validation logic.
