Environment variables in paths are not expanded

[memoakten]

Expected Behavior

Environment variables in paths are not expanded

1. in extra_model_paths.yaml base_path: $DATA_PATH\models

Should be expanded internally to whatever the environment variable $DATA_PATH references, with os.path.expanduser(os.path.expandvars(...)) (This is OS agnostic, because in python environment variables are always prefixed with $ no matter the OS)

2. The same issue also happens in command line args. e.g. python main.py --input-directory "$DATA_PATH\inputs" is not expanded. However there is a work around for this by expanding before passing. E.g. python main.py --input-directory "%DATA_PATH%\inputs". But there is no workaround for expanding the yaml contents.
