Enhancement

Since a lot of customers reported OOM when they are doing analyze table due to tidb_analyze_version = 2 in v5.1 and v5.2, and as this was defined as experimental feature, so we suggest not to use version 2 by default. Let's keep tidb_analyze_version = 1 as default set for v5.1.x and v5.2.x.

affected version: v5.1.x and v5.2.x.

I think it is an enhancement rather than a bug, so remove all the affects-xxx label.
