This actually causes more problems since there are a bunch of
places where we set the reason only if it was previously NO_REASON,
but we want to treat this the same way, i.e. untested. Adding
logic everywhere to clear and reset this value seem to create
too much overhead for very little value.

Previously partition priority was only considered when used as a
component of a job's priority with the priority/multifactor plugin.
Now the partition priority is considered first, as documented,
and the job priority is considered second.

There were a couple of cases where a job's reason
should have been set, but was not. In addition the
state_desc string should have been cleared in some
cases, but was not.

Plus clear a job's state_desc when the reason is set to NO_REASON

in 2.0 :)

Add --priority option to the salloc, sbatch and srun commands.

This code was originally put here to enforce checks to make sure jobs
didn't go over the limit.  If they didn't request the amount then we set
the limit and worked off that as if it were a request.

If we do this now we could get jobs deigned which would cancel the job at
submit with a very unrelated note as to why the job failed.

Since we now check this these limits after the node selection this isn't
needed.

In addition to accepting a job ID argument to the hold and release
commands also accept a job name (e.g. "scontrol hold my.bash")

Add a job's exit state (COMPLETED, FAILED, etc) and exit code to
email message

Added job reason of "SchedTimeout" if the scheduler was not able to reach
the job to attempt scheduling it.

Added SchedulerParameter of batch_sched_delay to permit many batch jobs
to be submitted between each scheduling attempt to reduce overhead of
scheduling logic.

I plan to make this configurable soon
