* Added support for string responses When a method/URL/response is defined to return string: - If no content types are define, default to 'text/plain' instead of 'application/json' - Add response handler, that returns the reponse string as-is if response content-type is 'text/plain' * Removed use of unused tag vendor tag - The tag was vendorExtensions.x-codegen-response.isPrimitiveType
