[Proposal] Support replace table feature

[morningman]

Is your feature request related to a problem? Please describe.
in #2663, I implemented a feature of Temporary Partition, so that users can use this function to
atomically write data to a partition. But this function is only for partition tables.

Therefore, here I have implemented a replacement table operation, which can perform atomic replacement of the table,
so that for non-partitioned tables, this method can also be used to achieve the purpose of atomic overwriting.

Syntax:

ALTER TABLE tbl1 REPLACE WITH TABLE tbl2;
