allow_experimental_map_type=1

[zhicwu]

Added the parameter in ClickHouseQueryParam. Since multi-statement SQL is now supported, you can alternatively execute below SQL in one run:

set allow_experimental_map_type=1;

create table if not exists system.test_map_support(
    m Map(UInt8, String)
) engine=Memory
