Spawned from https://github.com/apache/airflow/pull/15397#discussion_r635942246 This introduces a shim subpackage `airflow.compat` for all code to import from, instead of ad-hoc try-except. * 'airflow.compat.functools' module shims 'functools.cached_property' (using the third-party `cached_property` package) and 'functools.cache' (with `functools.lru_cache`). * The 'yaml' module was moved from `airflow.utils.yaml` and improved so we can always use it instead of importing `yaml` directly. --- **^ Add meaningful description above** Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/master/CONTRIBUTING.rst#pull-request-guidelines)** for more information.
