Add job record qos field and partition record allow_qos field.

This patch moves the QOS update of an existing job to be before the
partition update.  This ensures a new QOS value is the value used when
doing validations against things like a partition's AllowQOS and DenyQOS.

Currently if a two partitions have AllowQOS that do not share any QOS,
the order of updates prevents a job from being moved from one partition
to another using something like the following:

scontrol update job=<jobID> partition=<new part> qos=<new qos>

value for booleans.

Correct task layout with CR_Pack_Node option and more than 1 CPU per task.
Previous logic would place one task per CPU launch too few tasks.

Backfill scheduler now considers OverTimeLimit and KillWait configuration
parameters to estimate when running jobs will exit. Initially the job's
end time is estimated based upon it's time limit. After the time limit
is reached, the end time estimate is based upon the OverTimeLimit and
KillWait configuration parameters.

Backfill scheduler: The configured backfill_interval value (default 30
    seconds) is now interpretted as a maximum run time for the backfill
    scheduler. Once reached, the scheduler will build a new job queue and
    start over, even if not all jobs have been tested.
