Move "burst_buffer" from individual command data structures (srun_opt
  and salloc_opt) to common slurm_options. This is desired to have
  sbatch command support --bb option.

There was some development code accidentally included in the commit

Don't change the state when the RPC from slurmctld to slurmd is
  only queued

node_features/knl_generic - If plugin can not fully load then do not spawn

when a job requests no tasks and more memory than MaxMemPer{CPU|NODE}.

e.g.
sbatch --wrap="sleep 10"

This will give expected results. Found while working on Bug 4515.

And print an appropriate fatal error message rather than relying
upon random errno value.

Based off of Ryan Cox's original contribs/pam_slurm_adopt/README.

Bug 3567.

In the federation case, the origin job is completed in the database when
a sibling job starts the job. The complete message is then sent again to
the database when the job is completed on the sibling cluster but
it is updated with the sibling job's exit code.

The jobcomp plugin didn't handle the multiple updates to the record.
This change allows the existing record to be updated.

Bug 4500

The pid files in slurm.conf and the systemd service files must match,
or systemd will time out looking for the wrong pid file. Currently,
the Cray slurm.conf template has different pid files for slurmctld and
slurmd than the service files.

There's no reason for us to use these nonstandard pid files, and it
will save us some headaches to switch over.
