Description
This is based on discussions with leftnoteasy in YARN-6979.
In YARN-6979, the getContainersToDecrease() and addAllContainersToDecrease() methods were removed from the NodeHeartbeatResponse (although the actual protobuf fields were still retained). We need to ensure that for clusters that upgrade from 2.8.x to 2.9.0, the decreased containers should also be sent to the NM.
