This patch finally resolves absolute/relative CPU mapping for nodes
where the NUMA (or sockets) have different core counts (e.g. KNL SNC4).

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.

Bug 3049.

Check if node names are contiguous with respect to the node list
assigned to the partition, rather than just monotonically increasing.

Bug 3006.

xcgroup_delete will print a log message if there is a problem.

node_features/knl_cray plugin: Increase default CapmcTimeout parameter from

bug 3100

capmc_suspend/resume - If a request modify NUMA or MCDRAM state on a set of
    nodes or reboot a set of nodes fails then just requeue the job and abort the
    entire operation rather than trying to operate on individual nodes.

Allow a node's PowerUp state flag to be cleared using update_node RPC.
bug 3100

When powering up a node to change it's state (e.g. KNL NUMA or MCDRAM mode)
    then pass to the ResumeProgram the job ID assigned to the nodes in the
    SLURM_JOB_ID environment variable.

Don't log error for job end_time being zero if node health check is still
    running.

Restore ability to manually power down nodes, broken in 15.08.12
in commit b4904661

The patch introduced in commit b4904661 (not powering down dead node) has a bad side effect.  Adding the "(node_ptr->last_idle != 0)" condition prevents from powering down nodes with the following command:

scontrol update nodename=nX state=power_down

because the state update function relies on zeroing the "last_idle" variable when a power_down is requested (see src/slurmctld/node_mgr.c, line 1589).

Reverting this commit should solve the problem...but I let you decide...

bug 3093

node_features/knl_cray: If a node is rebooted outside of Slurm's direction,
    update it's active features with current MCDRAM and NUMA mode information.
bug 3071

Fix race condition that could result in MCDRAM state information coming
  from capmc rather than cnselect (used state for next boot rather than
  latest boot).
bug 3080

No functional change, just silencing the warning message in this instance.

Fix some whitespace on line endings while here.

Add Slurm overview by Alex on first day, move KNL to second morning,
shift roadmap to right after lunch.

bug 3065

Previous cap was 2 sec (default TCP timeout) times the node count
  and divided by 1000. A 9000 node job would have the messages
  spread out over 18 seconds. This change caps the spread at
  5 seconds and assumes the normal TCP logic can handle the rest
