Cannot use ClusterName without reading a config file
that may not exist.

Bug 3026.

This introduced an inadvertent dependency on the config file,
which does not exist when setting up a new cluster.

This reverts commit c39f9ac9.

task/affinity plugin: Honor a job's --ntasks-per-socket and
    --ntasks-per-core options in task binding.
bug 3118

Preserve non-KNL node features when updating the KNL node features for a
    multi-node job in which the non-KNL node features vary by node.

node_features/knl_cray plugin: If the reconfiguration of nodes for an
    interactive job fails, kill the job (it can't be requeued like a batch job).

node_features/knl_cray plugin: Add separate thread to interact with capmc
    in response to unexpected node reboots.

bug 3091

Prevent possible divide by zero in select/cons_res if a node's board count
    is higher than it's socket count.
bug 3155

If a node's socket or core count are changed at registration time (e.g. a
    KNL node's NUMA mode is changed), change it's board count to match.
bug 3155

Cray: The slurmd can manipulate the socket/core/thread values reported based
    upon the configuration. The logic failed to consider select/cray with
    SelectTypeParameters=other_cons_res as equivalent to select/cons_res.
bug 3155

abs() should not be used on long long variables as it would
truncate if strictly confirming to C99. Use llabs() instead.

Fix to commit 2aefc66b.

node_features plugin - Add "mode" argument to node_features_p_node_xlate()
    function to fix some bugs updating a node's features using the node update
    RPC. Without this change it is impossible to clear the active features of
    a node or reset non-KNL node features.

node_features/knl_cray plugin: Substantially streamline and speed up logic
    to load current node state on reconfigure failure or unexpected node boot.
    Completely eliminate capmc calls and just use cnselect to load current
    node mode information.

node_features/knl_cray plugin: drain any node not reported by
    "capmc node_status" on startup or reconfig. Also re-tests
    on failed node restart for job.

node_features/knl_cray plugin: Remove any KNL MCDRAM or NUMA features from
    node's configuration if capmc does NOT report the node as being KNL.
    For example, we don't want a non-KNL node with features="quad,cache".

Add new knl.conf configuration parameter CapmcRetries
Modify capmc_suspend and capmc_resume to retry operations when
  Cray State Manager is down.
Add retry logic to node_features/knl_cray to handle Cray State
  manager being down.

Otherwise they'll truncate when packed into the RPC and end up
as some bizarre value at the controller.

Bug 3098.

Set completed time for pending/running runaway jobs to the max of
(start, eligible, submit) times.

Bug 3075

Avoid using slurm_forward_data because it causes thread spawn that
introduces unwanted delays.

Bug 3102.

Also correct the value of NICE_OFFSET used within the perl API.

Bug 3098.

Bug 3051.

Otherwise updates would be rejected for running jobs even if there
would be no impact. Most common when the job_submit plugin is overriding
QOS/GRES values on everything; without this change an update to "comment"
or other fields would fail with ESLURM_JOB_NOT_PENDING.

Bug 3117.

Never ever run NHC, even on an edge case that NHC_NO would still launch NHC
after.

Bug 3105.

Switch to list_for_each, and check if access list actually changed
after each update before updating last_prat_update. This prevents
the backfill scheduler from resetting mid-cycle unnecessarily.

Bug 3123.

Add "sbatch_wait_nodes" to SchedulerParameters to control default sbatch
    behaviour with respect to waiting for all allocated nodes to be ready for
    use. Job can override the configuration option using the --wait-all-nodes=#
    option.
bug 3120

Prior logic would treat execute line like this:
$ sbatch --wait-all-nodes -N3 tmp
with "-N3" as being the argument to the "--wait-all-nodes" option.
See bug 3120

Add salloc/sbatch/srun option --use-min-nodes to prefer smaller node counts
    when a range of node counts is specified (e.g. "-N 2-4").
bug 2996

Add salloc/sbatch/srun --priority option of "TOP" to set job priority to
    the highest possible value. This option is only available to Slurm operators
    and administrators.

bug 3090

Make sure no attempt is made to schedule a requeued job until all steps are
    cleaned (Node Health Check completes for all steps on a Cray).
bug 3082

Otherwise limit is checking the node count against the midplane count.
