 o remove slurm-* files during make distclean

   binaries (use --with debug on the rpm command line)

   confusion with real regular expressions.

Add new scontrol command "ping", report up slurmctld daemons when getting config.

job_cancel arrives. job/step complete RPCs will now return job completed
