Previous logic would set the avail_node_bitmap when
a node was powered down, even if the initial state was
DOWN or DRAINED. This made the node available for allocation
to a job, which we don't want until the DOWN or DRAIN
state is cleared.

Bug 1867

This problem is reproducible by launching a job then killing the
  slurmstepd process. Under those conditions, requeue the job if
  possible (i.e. batch job with requeue option/configuration).
  This patch also improves the slurmctld logging when this happens.
bug 1889

Correct RebootProgram logic when executed outside of a maintenance
  reservation. Previous logic would mark the node up upon response
  to the reboot RPC (from slurmctld to slurmc) and when the node
  actually rebooted, flag that as an unexpected reboot. This new
  logic checks the node's up time to not mark the compute node as
  being usable until the reboot actually takes place.

association manager.

Prevent job array task ID from being reported as NO_VAL if last task in the
  array gets requeued. The problem is that when that task starts, the task
  bitmap entry for it stays set, but the task counter gets decremented.
  If that job then gets requeued, under some conditions a failure to schedule
  it results in the array_task_id in the job record getting set to NO_VAL.
  Then when building the job info to report for squeue/scontrol, the string
  showing the pending task ID's is not rebuilt due to that counter being
  zero. All indications are that the job runs fine, only the information
  reported to squeue/scontrol is wrong.
