If GRES configuration data is unavailable from gres.conf, then use the
    node's "Gres=" information slurm.conf. This will eliminate or minimize the
    gres.conf file in many situations.
bug 6761

In 0e149092 not setting the variable when job was not requesting any gres
was considered a bug. The cuda API will use all devices if the variable is
not set. If it is set to some unknown or empty value, it will use no devices.
This variable should be used only for testing purposes and ConstrainDevices=yes
in cgroup is recommended.

Bug 6412

gres plugins will setup environment for every gres in the system even if the
job has not requested it.

Bug 6412

Removed linear search, replaced with direct record references and a hashmap.
This is faster and avoids potential collisions between assoc id's and user id's.

Change to %pJ identifier while here and merge different partition
priorities into a single log message line.

Regression from enhancement 4506.

Bug 6680

Bug 6662

Previously the state reason could remain as WAIT_NO_REASON even after
backfill evaluation. This should improve system feedback/responsiveness
user perception.

Continuation of 69d78159

Bug 6500

Issue was from ade9101e.

The problem was an over simplified if statement which when ran multiple
times would set the start time incorrectly.

Bug 6697

Even if main scheduler doesn't allocate resources for hetjobs, the
queue list should be composed by all types of jobs. Otherwise, lower
priority regular jobs could be allocated resources by main scheduler
while higher priority hetjobs are waiting for a backfill cycle.

This reverts commit 082c59dd.

Bug 6286

Instruct the backfill scheduler to attempt to start a heterogeneous job
as soon as all of its components are determined able to do so.

Bug 5579.

I neglected to add a pre4 section after tagging pre3.

There are at least two points where this can return a false positive
error message which can be confusing for users.

This used to be the short form for --account, but was changed to
-A ahead of the Slurm 2.1 release over nine years ago.

Backport of 21b9a39b

Bug 6625

Never called. None of the plugins have bothered to implement this correctly.
The jobcomp/script plugin comes closest, but did not pick error codes within
the designated range.

Bug 3647.

Leave the state file name - burst_buffer_cray_state alone.

Bug 6440.

Print error: for each new line.

Bug 6584

response_cluster_rec stored a pointer to data in the controller config
that gets freed when the controller is reconfigured.

Bug 6584

This should never happen, but is a nice safeguard.

Bug 6566

The int size may not be enough when converting from seconds to usec for the
maximums defined for bf_interval. _yield_sleep has been to adapt to this change
too.

Bug 6401

All numeric backfill parameters have now maximums and minimum values.
