Add padding characters to the value if needed.

        Args:
          value: The string value to be padded.
          pad_len_multiple: Pad the result so its length is a multiple
              of pad_len_multiple.
          pad_char: The character to use for padding.

        Returns:
          The string value with padding characters added.
