rxgraph and rosnode get the info from the same place.

The feature to "kick out" is in development and requires developing
new features like TTL settings for registrations. As a workaround,
you can call "rosnode cleanup" or checkout the 'reaper' node. I'll
note that none of this should really affect the functioning of your
system.
