Subject: [PATCH] [ENG-4647] Fix env_file handling (#4805)

* [ENG-4647] Fix env_file handling

* Import dotenv.load_dotenv early to avoid ImportError while loading
  rxconfig.py
* Read ENV_FILE from the environment explicitly.

fix #4803

* Config.Config: use_enum_values = False

Save enum fields as the enum object rather than the value.
