-------------------------------

Sorry for jumping in little late here. Thanks for the effort [~GergelyNovak] 
and [~eepayne]. Patch seems fine.

One quick doubt. In {{ProportionalCapacityPreemptionPolicy}}, LOG is printed 
when {{csConfig}} is not null. So how could we quickly verify which config got 
changed?

> At least the properties for {{max-allowable-limit}} and {{minimum-threshold}} 
> should be refreshable. It would also be nice to make 
> {{intra-queue-preemption.enabled}} and {{preemption-order-policy}} 
> refreshable.
