NOTE: This patch would modify all Backend's data. And this will cause a very long time to restart be. So if you want to interferer your product environment, you should upgrade backend one by one. 1. Refactoring be is to clarify the structure the codes. 2. Use unique id to indicate a rowset. Nameing rowset with tablet_id and version will lead to many conflicts among compaction, clone, restore. 3. Extract an rowset interface to encapsulate rowsets with different format.
