Is your feature request related to a problem?

For some DDL like alter table rename column, we skip all dml and ddl for that shard table until all shard tables meet the same rename column statement in optimistic mode. However, some user use optimistic mode in test environment and want to know the incompatible DDL immediately.

Describe the feature you'd like

add a config item strict-optimistic-shard-mode, when we meet DDL like alter table rename column, return the error immediately.

Describe alternatives you've considered
