After the new node is added, the data on the old node is not migrated. If the new node is removed soon, the data will be inconsistent

Consider adding a Delete API?

这个项目只是一个玩具项目。在实际生产中，一份数据不可能只缓存在一个节点上，在geek-cache中，访问节点的请求会经过一致性哈希落到哈希环中的某个节点上，当这个节点宕机，缓存在该节点的数据将失效，新的请求经过映射后会映射到其后的一个节点之上。我们可以考虑将一致性哈希做在proxy层，将geek-cache再抽象化，哈希环中的每个节点都是一个集群，通过QuorumNWR算法来实现自定义的一致性，当然，这只是个idea，具体的实现还需要进一步讨论。

解决基本一致性问题，缓存key与哈希值，监听虚拟节点通知，对自有key进行管理。 @leaf-dawn
