author: lixin/longda Dedicate Topology status Topology status: active/inactive/killed/rebalancing killTimeSecs: when status isn't killed, it is -1 and useless. when status is killed, do kill operation after killTimeSecs seconds when status is rebalancing, do rebalancing opation after delaySecs seconds restore oldStatus as current status
