      Description

      There're a couple of JIRAs open for multiple resource types preemption in CS. It might be better to group them to make sure everybody is on the same page. 

      In addition to that, I don't believe our preemption logic can properly handle multiple resource type preemption when YARN-5881 is being used. (Different percentage of shares for different resource types). We may need some overhaul of the preemption logics for that.
