* Refactor Docker launcher's configuration setup and file handling

This commit refactors the configuration setup and file handling in the Docker launcher. It introduces a new `FileSystemManager` class with methods to ensure the existence of directories and files. The `ensure_dir` method is used to create the `temp` directory if it doesn't exist, and the `ensure_file` method is used to create the `.env` file with default content if it doesn't exist. This improves the reliability and maintainability of the Docker launcher.

* Add class_registry and python-dotenv lib

* Refactor Docker launcher's dependency installation and file handling

* Update docker/msdl/templates/backend/cloud_llm.dockerfile
