Distinguish between job and step IDs in sbcast (or srun --bcast)
  logs.

bug introduced in commit 06b54823

Added srun option of --bcast to move executable file to compute nodes

burst_buffer/cray: Support file staging when job lacks job-specific buffer
    (i.e. only persistent burst buffers).
bug 2113

No change to document contents, just reorded the fields documented.

bug 2143

Always log some operations (previously logging was only triggered
  by long run time of the operations)
Log some operations with info() rather than debug() for DebugFlags=
  burstbuffer

test more association/qos limits before reserving resources for a
  pending job. This complements commit dcc943b7

Backfill scheduler: Test association and QOS node limits before reserving
    resources for pending job.

Bug 1493

Prevents the following sequence from causing a segfault:
$ scontrol create partitionname=stuff nodes=ALL
$ sbatch --wrap="hostname" -o/dev/null -p stuff
Submitted batch job 1047468
$ scontrol delete partitionname=stuff
$ scontrol update jobid=1047468 partition=stuff

tree.

Previously only SlurmUser could do so.

cgroup system for the extern step.  This needs to happen for accounting
purposes, but also makes things simplier.

step.

Test if job is pending before looking at burst buffer specs when
building the job queue. This should result in a slight speedup in
the job scheduling logic.
