Update some node feature logic to support KNL nodes.

If a user submits a job with duplcate partition names (e.g.
  "sbatch --partition=debug,debug,debug", slurm was creating

uint32_t new_cpus = detail_ptr->num_tasks
	/ detail_ptr->cpus_per_task;

The / should had been * this whole time.  This was the reason we found
this in the first place.

  srun: job 1332712 has been allocated resources

Expand documentation for advanced reservation Purge_Comp flag in
  scontrol man page, add to advanced reservation web page, increase
