下线dp分片

将目标节点上的指定data partition分片下线，并自动转移至其他可用节点

./udbto-cli datapartition decommission [Address] [Partition ID]   

Decommission data partition successfully

新增dp分片

在目标节点新增一个data partition分片

./udbto-cli datapartition add-replica [Address] [Partition ID]

Add replication successfully

删除dp分片

删除目标节点上的data partition分片

./udbto-cli datapartition del-replica [Address] [Partition ID]    

Delete replication successfully
