@emersonknapp In general LGTM.
I am thinking that now the node name became autogenerated by default and it will be difficult to figure out what it is to send service requests from the command line.
It would be very handful to output the final node_name to the LOG_INFO() stream at least.

Nitpick, need to remove extra "for".

Fixes #425
Copies same approach from https://github.com/AAlon/ros2cli/blob/master/ros2cli/ros2cli/node/direct.py#L37
Adds a
--node-nameoption to all verbs that create a ros2 node. Defaults toprefix_PIDby using Pythonos.getpid(). This way all running players/recorders will have locally unique names by default. "Locally" because within the local machine the PID will be unique, but may not be within a multi-machine system. In this case it probably pays to be explicit anyways, and the--node-nameoption allows for that.
