sched/backfill: This change moves some logic used to support the
   bf_min_age_reserve configuration parameter for slightly better
   performance.

Correct job task count calcuation if only node count and ntasks-per-node
    options supplied.

SchedulerParameters now accepts keyword of "max_rpc_count" in
  addition to the documented "max_rpc_cnt"

Added #define JOB_SHARED_* varilables to slurm.h
Replaces some blocks of spaces with tabs
Remove test of MCS_Plugin from client where job is submitted as
  a means of determining if an --mcs-label option is supported.
  This will not work for jobs being submitted between systems,
  which will become common in slurm v16.05. The check will need
  to be performed in the (slurmctld) server.

There were some changes required to the un/pack logic due to
  patch not working correctly and/or the newer version of Slurm
  the patch was applied to.

Only a super user can change Slurm configuration.
Exit immediately if the test can not be run.

- add new configuration parameters MCSPlugin and MCSParameters
  (MCS logic can be disabled/enabled/enabled-on-demand)
- add mcs_label to jobs and nodes related structures
- add --mcs-label option to srun,salloc,sbatch as well
  as MCS information in the various Slurm commands
- initial none/user/group MCS plugins
- add squeue/sinfo optional filtering based on MCS labels

This would have helped to identify the performance issue associated
with bug 2174
