      A utility function that asks a question to the user to get an answer, potentially looping until it gets a valid
      answer.
  
      Args:
          question (`str`): The question to ask the user.
          default_value (`str`, *optional*): A potential default value that will be used when the answer is empty.
          is_valid_answer (`Callable`, *optional*):
              If set, the question will be asked until this function returns `True` on the provided answer.
          convert_to (`Callable`, *optional*):
              If set, the answer will be passed to this function. If this function raises an error on the procided
              answer, the question will be asked again.
          fallback_message (`str`, *optional*):
              A message that will be displayed each time the question is asked again to the user.
  
      Returns:
          `Any`: The answer provided by the user (or the default), passed through the potential conversion function.
