> Currently, grouping by alias or ordinal is not supported, but sometimes it can be handy. 
> Some DB vendors support this feature (PostgreSQL, MySQL), but some not (Oracle, MSSQL). In the current Ignite H2-based SQL engine, this feature is not supported. We should decide do we need it in Ignite with calcite-based SQL engine.
> This feature can be easily enabled by redefining {{SqlConformance#isGroupByAlias}}, {{SqlConformance#isGroupByOrdinal}}
> Affected tests:
> {{src/test/sql/aggregate/group/test_group_by.test}}
> {{src/test/sql/aggregate/group/test_group_by_alias.test}}
> And many other.
