   Hi,
   
   This is an enhancement function for query optimization. It is not a difficult one, welcome your contribution.
   
   ### Target
   Add corresponding SqlConformanceEnum and Lex to the properties of Calcite by `ShardingSphereMetaData` in `CalciteContextFactory`.
   
   ### Items
   - Get `DatabaseType` from `ShardingSphereResource` of `ShardingSphereMetaData`
   - Get the corresponding type value from `SqlConformanceEnum`
   - Get the corresponding type value from `Lex`
   - Put the two values above into `Properties` in `createProperties()` of `CalciteContextFactory`
