> Before YARN-1964, Container-script generation was fundamentally driven by ContainerLaunch object. After YARN-1964, this got pulled into ContainerExecutor via the {{writeLaunchEnv()}} method which looks like an API, but isn't.
> In addition, DefaultContainerExecutor itself has a plugin {{LocalWrapperScriptBuilder}} which kind of does the same thing, but only for Linux/Windows.
> We need to have a common API to override the script generation for Linux/Windows/Docker etc.
