由于对节点做更改操作后, 可能cluster nodes没有立刻反应修改的东西(如之前发现的加了节点后, cluster nodes里面有一瞬间还没改), 导致现在的一致性检查(cluster.wait)可能存在这样的bug:

对节点做了更改操作
操作完成后, 所有节点在一瞬间响应的cluster nodes没有更改, 跟之前一样.
wait的consistent检查在这一瞬间通过, 但是再后面的consistent检查中, 某些节点的cluster nodes开始反应有更改了, 这样后续的consistent操作就会不通过.

实验过, 也查过redis代码了, 槽位更改后, cluster nodes会立刻反映新的槽位信息.
