          :param str entity: The name of the entity.
          :param str value: The text of the entity value. This string must conform to the
          following restrictions:
          - It cannot contain carriage return, newline, or tab characters.
          - It cannot consist of only whitespace characters.
          - It must be no longer than 64 characters.
          :param dict metadata: Any metadata related to the entity value.
          :param str value_type: Specifies the type of entity value.

          specify either synonyms or patterns (depending on the value type), but not both. A

          specify either synonyms or patterns (depending on the value type), but not both. A
          pattern is a regular expression no longer than 512 characters. For more
          information about how to specify a pattern, see the
