add completion for parameter name arguments

[dirk-thomas]

For the get and delete verbs. Also naming the argument parameter_name (rather than name) in the usage.

My sole concern is response latency. How long does it take to provide suggestions? I ask because I've seen ros2 topic almost blocking while retrieving topics. DirectNode brings up a node on construction and tears it down on context leave -- maybe keeping it around may speed up subsequent queries, not the first though.

Also, why not adding completion for the set verb?

It takes as long as it takes to spin up the node and wait for the service.

In this case the delay happens when you use completion. If you don't it doesn't affect the call.

It would be great if instead this information would be queried over the node daemon but that kind of API is not available atm.

Added in 96bee44.

Yeah, that's what I was thinking of. Alright, food for thought.
