1. Do not start a second copy of the event scheduler. This is the cause
   of all the slurm error messages on the APT cluster. Clearly this was
   wrong for DeleteNode(). AddNode is still open for debate, but at
   least now the error mail will stop.

2. Do not reset the startstatus either, this was causing web interface
   to think startup services were running, when in fact they are not
   since the other nodes are not rebooted. In the classic interface,
   node reboot does not change the startstatus either, so lets mirror
   that in the Geni interface.
