Remove duplicate backfill scheduling tests. For example there is
no need to test if a job can be started if the only difference
from the previous test involves nodes in other partitions that
can not be used by the job we are trying to start.

The backfill scheduler was always reporting the time that a job
was being considered as NOW rather than the time that was really
being considered.

decreases and total is less than in use.

This is a correction to commit 308b7432

Improve how failures in slurmd/slurmstepd communications are logged.

mail messages for job array events print now use the job ID using the
format "#_# (#)" rather than just the internal job ID.

Cray network.

Cray/ALPS system - Enable backup controller to run outside of the Cray to
accept new job submissions and most other operations on the pending jobs.

* Handle a missing ALPS spool directory
* Update debug statements to work like the switch plugin
* Move some code into static functions
* Keep track of the number of active job steps and call

Add child_forked() function to the slurm_acct_gather_profile plugin to
close open files, leaving application with no extra open file descriptors.

If the backup slurmctld assumes primary status, then do NOT purge any
job state files (batch script and environment files) but if any attempt
is made to re-use them consider this a fatal error. It may indicate that
multiple primary slurmctld daemons are active (e.g. both backup and primary
are functioning as primary and there is a split brain problem).
