queuewise premption counts preempted job + preempting job as 1 slot

For example, rqs 'hosts {*} to slots=$num_proc' will allow jobs to 
run in the subordinate queue and in the superordinate queue.

Also for example, setting host complex_values slots=n will allow
n subordinate jobs + n superordinate jobs.

slotwise preemption counts preempted job + preempting job as 2 slots

In slotwise, rqs 'hosts {*} to slots=$num_proc' total jobs in sub and
superordinate queue instances will not exceed $num_proc.

Also in slotwise setting host complex_values slots=n will allow
only n jobs to run in both superordinate and subordinate queue instances.

This makes slot control via rqs or host complex value impossible and
prevents the addition of a queue instance on a host that is not in
the super/sub ordinate hierarchy.
