Hi [~leftnoteasy]
Uploading an initial version of patch.
*testExpireKill* already handles the verification of this change. Multiple
PREEMPT_CONTAINER event will not be raised for same container for each interval
check of ProportionalCPP.
> Proportional Preemption policy should try to avoid sending duplicate
> PREEMPT_CONTAINER event to scheduler

>
> Currently ProportionalCPP tries to send multiple PREEMPT_CONTAINER events to
> scheduler during every cycle of preemption check till the container is either
> forcefully killed or preempted by AM.
> This can be throttled from ProportionalPreemptionPolicy to avoid excess of
> events to scheduler.
