缩容tikv节点后，状态是成功，但是重启tidb的时候，依然还是会试图启动这个节点
重试缩容：
Error: failed to scale in: no endpoint available, the last err was: error requesting http://172.29.29.16:2379/pd/api/v1/store/4, response: “[PD:core:ErrStoreTombstone]store 4 has been removed”
, code 410
重启：
Error: failed to start tikv: failed to start: 172.30.30.136 tikv-20160.service, please check the instance’s log(/data/tidb-deploy/tikv-20160/log) for more detail.: timed out waiting for port 20160 to be started after 2m0s
节点状态如下：
172.30.30.136:20160 tikv 172.30.30.136 20160/20180 linux/x86_64 Tombstone /data/tidb-data/tikv-20160 /data/tidb-deploy/tikv-20160
如何彻底下线？
