Remove unused function acct_policy_node_usable() from src/slurmctld/acct_policy.c

Prevent associations from being delete if it has any jobs in running,
pending or suspended state. Previous code prevented this only for running
jobs.

PluginDir is a path. It shouldn't be an error to have duplicate
plugins in your path. Plus, the error is not helpful because it
doesn't specify which path is not being loaded. Therefore, just
remove the error and load the first plugin in the path as expected.

Fix bugs in sched/backfill with respect to QOS reservation support and job
time limits. Patch from Alejandro Lucero Palau (Barcelona Supercomputer Center).

Fix to GRES allocation logic when resources are associated with specific
CPUs on a node. Patch from Steve Trofinoff, CSCS.

not give correct results on these systems.

admin sets the state to error.

Change default value of StateSaveLocation configuration parameter from
/tmp to /var/spool, where the files are less likely to be purged.

Modify slurmdbd.conf parsing to accept DebugLevel strings (quiet, fatal,
info, etc.) in addition to numeric values. The parsing of slurm.conf was
modified in the same fashion for SlurmctldDebug and SlurmdDebug values.
The output of sview and "scontrol show config" was also modified to report
those values as strings rather than numeric values.

Advise use of the logrotate tool in order to avoid SLURM log files
from growing too large. Patch from Rod Shultz, Bull.

Do not treat the absence of a gres.conf file as a fatal error on systems
configured with GRES, but set GRES counts to zero. These counts can be
Counts can be altered by node_config_load() in the gres plugin.

If KillOnBadExit is configured to 1 and an srun task exits with a
non-zero exit code then report the correct termination reason
NonZeroExitCode rather than Cancelled.

Add the ability to reboot all compute nodes after they become idle. The
RebootProgram configuration parameter must be set and an authorized user
must execute the command "scontrol reboot_nodes". Patch from Andriy
Grytsenko (Massive Solutions Limited).

Note that a job's size factor in setting priority is based upon node
or CPU count.

Add the ability to read the slurm.conf file across a network using
the accounting_storage plugin. The accounting_storage/slurmdbd plugin
does require modification for this functionality to fully operate.
Patch from Andriy Grytsenko (Massive Solutions Limited).

The slurmctld code that processes job notify messages unecessarily
restricts these messages to be from the slurm user or root. This
patch allows users to send notifications to their own jobs.
