param list -t for consistency

[JuliusSustarevas]

#96 Feature request
ros2 topic list
and
ros2 service list
have the -t parameter to show types. But ros2 param list does not. It would be convinient and consistent if it did.

Feature description

"ros2 param list -t" could return param names followed by types

"ros2 param list -t" could return param names followed by types

While I like the idea of the feature, I think we may want to use a different flag than -t. The -t flag implicitly means print the ROS message type, which is not what you are asking for. Instead, you are asking for the internal stored type of the parameters. I'll just throw out --param-type as a flag idea for now, but maybe others disagree.

In any case, while I think this is a great idea, I don't think we're going to have time to work on it right now. But if you'd like to contribute a change to add it, we'd be happy to review it.

Thanks for the report.

Well I personally always wanted params to be ROS Message type which gives a certain nice consistency. You could set some param as a Pose message, set your deadzone speed as a Twist Message etc. But thats a separate feature request i guess
