Creates an AppConfig extension. An extension augments your ability to inject logic or behavior at different points during the AppConfig workflow of creating or deploying a configuration.

You can create your own extensions or use the Amazon Web Services authored extensions provided by AppConfig. For most use cases, to create your own extension, you must create an Lambda function to perform any computation and processing defined in the extension. For more information about extensions, see Working with AppConfig extensions in the AppConfig User Guide.
