> Currently {{SearchRateTrigger}} generates events when search rate thresholds
> are exceeded, and {{ComputePlanAction}} computes ADDREPLICA actions in
> response - adding replicas should allow the search rate to be reduced across
> the increased number of replicas.
> However, once the peak load period is over the collection is left with too
> many replicas, which unnecessarily tie cluster resources.
> {{SearchRateTrigger}} should detect situations like this and generate events
> that should cause some of these replicas to be deleted.
> {{SearchRateTrigger}} should use hysteresis to avoid thrashing when the rate
> is close to the threshold.
