New node config is generated properly but not applied automatically (can be done with a qconf -Ae <filename>)

Once we are confident about turning on qconf from puppet, this should be automatic. There remains an issue for which no clear solution exists: normally, the gridengine-exec service must be (re)started on the newly added node after the node is known to Gridengine; but because of the way we have to collect data from instances and create the configuration centrally from tools-master, it's not clear how to signal the restart to the exec node.

Right now, this is worked around by doing the restart by hand.
