> {{SchedulingEditPolicy#init}} doesn't need to take interface {{PreemptableResourceScheduler}}
as the scheduler input. A ResourceScheduler is good enough. With that change, fair scheduler
is able to use scheduling monitor(e.g. invariant checks) as CS does. Further more, there is
no need for interface {{PreemptableResourceScheduler}}.
