slots迁移

之前集群有3个master，每个master的slots的数量为16384/3。目前新增一个，则每个master为16384/4=4096个slots，所以之前的master节点分别需要迁移1365,1365,1366个slot给新节点

开始reshard迁移

在执行reshard时有两种迁移slots方式：

  • 输入指定master实例id：指定master实例节点迁移指定数量slots到某master实例节点
  • 输入all：从所有master实例节点总共迁移指定数量slots到某master实例节点
# 此处演示指定实例的迁移方式，下面这种方式等同于all
