Rename 后会丢失原表的元素

Is this a regression?

Yes

Description

rename 过程中只是单纯的把原表的metadata发给新表，没有把原表的元素也发转给新表

元素放到rocksdb的时候那个key是包含表名的，不只是metavalue的东西，但rename之后没有改变这个原有的表名，用新表名也凑不出这个key，导致的就是元素丢失了

粗略看了一下，应该不止list类型，其他类型也有，此外，还有renamenx命令也存在这个问题

After a cursory look, it seems that there are not only list types, but also other types. In addition, the renamenx command also has this problem.

按照当前的存储结构，可能会存在一个问题，就是原有的数据如果比较多的时候，rename可能会存在性能问题

After a cursory look, there should be more than just list types, but other types as well. In addition, the renamenx command also has this problem.

According to the current storage structure, there may be a problem, that is, if there is a lot of original data, rename may have performance problems.
