  """Loads Actions from the actions directory, and instantiates them.

  Args:
    filters: list, strings with names of action classes to load. Loader will
        skip classes not listed. In the absence of this list no filters are
        applied.
    log_exceptions: bool, whether to supress exceptions and log their messages
        instead.

  Returns:
    A dictionary of actions, with their names as keys and instaniated Action

  Raises:
