Change references to reconfigure_gui to use rqt

Seems we have some system calls to the old reconfigure_gui.
- Selecting the "Advanced options" menu on a segmented object cluster fails with the message:

```
Running system command: rosrun dynamic_reconfigure reconfigure_gui /interactive_marker_node
reconfigure_gui has moved!

 Try: rosrun rqt_reconfigure rqt_reconfigure
```
