**Usage**
Postgres, MySQL, and Oracle support the expression `LEFT JOIN ... ON 1 = 1`, but ClickHouse does not.

It may be possible to replace `LEFT JOIN ... ON 1 = 1` with `CROSS JOIN`, but I want to use the query in the same form for lots of databases.

Please support the expression `LEFT JOIN ... ON 1 = 1`.


**Detailed SQL**
```SQL
CREATE TABLE test
(
    `name` Nullable(String),
    `id` int
)
ENGINE = Log();

insert into test values ('a', 1) ('b', 2) (null, 3);

select * from test t1 left join (select * from test ) t2 on 1 = 1   
-- DB::Exception: Not equi-join ON expression: 1 = 1. No columns in one of equality side.: While processing 1 = 1.
```

    {
        if (table_join.strictness == ASTTableJoin::Strictness::Any)
            if (table_join.kind == ASTTableJoin::Kind::Full)
                throw Exception("ANY FULL JOINs are not implemented.", ErrorCodes::NOT_IMPLEMENTED);
    }
    out_table_join = table_join;
}

    assert(tables.size() >= 2);

        const auto & keys = table_join.using_expression_list->as<ASTExpressionList &>();
        analyzed_join.addDisjunct();
        for (const auto & key : keys.children)
            analyzed_join.addUsingKey(key);
    }
