1. Dropped support for DatabaseOrdinary for MaterializeMySQL. It is marked as experimental, and dropping support makes the code more maintaible, and speeds up integration tests by 50%. 2. Get rid of thread name logic for StorageMaterializeMySQL wrapping, use setInternalQuery instead (similar to MaterializedPostgreSQL).
