class_docstr: Class that manages configuration files for a DVC repo.
  
  Args:
      dvc_dir (str): optional path to `.dvc` directory, that is used to
          access repo-specific configs like .dvc/config and
          .dvc/config.local.
      validate (bool): optional flag to tell dvc if it should validate the
          config or just load it as is. 'True' by default.
  
  Raises:
      ConfigError: thrown if config has an invalid format.
code: def load_file(path, fs=None) -> dict:
      from configobj import ConfigObj, ConfigObjError
  
      from dvc.fs import localfs
  
      fs = fs or localfs
  
      with fs.open(path) as fobj:
          try:
              conf_obj = ConfigObj(fobj)
          except UnicodeDecodeError as exc:
              raise ConfigError(str(exc)) from exc
          except ConfigObjError as exc:
              raise ConfigError(str(exc)) from exc
  
      return _parse_named(_lower_keys(conf_obj.dict()))
