• ros2 action info

Action: /fibonacci

TODO

• provide consistent format without --verbose option to print the action type instead.
• add --verbose option to print the node name, namespace, and endpoint type. (we do not have QoS for action endpoint or type hash)
• rcl_action_count_clients / rcl_action_count_servers should be introduced.
