 Action introspection is disabled by default, so users need to enable it with ``action_server_configure_introspection`` parameter when the server starts up.
 In this demo, ``FibonacciActionServer`` enables action introspection when the value of the ``action_server_configure_introspection`` parameter is ``contents``.
