/**
 * Controller mixin for authentication-agnostic login: defines the application at runtime to use the authentication method

 * Some authentication methods (eg cookies) are not available to third-party applications.
 * This has limited use, since most applications will only need to support one method. It may be useful for ember apps
 *   that run inside the OSF, eg to use the standalone dev server, or to offer support for branded apps
 *   on third-party domains.
