Subject [GitHub] incubator-quickstep issue #234: Add protobuf support for UNION ALL operator.

    @Terranlee Unfortunately, I observed some non-deterministic results for the following
two queries in `quickstep_queryoptimizer_tests_executiongenerator_select_distributed`.
    
    So I suggest to create a new test for `union` in the single-node mode only.
    
    ```
    SELECT int_col AS result FROM test
    WHERE int_col < 5
    UNION
    SELECT int_col + 3 AS result FROM test
    WHERE int_col < 5;
    
    SELECT float_col FROM test
    WHERE int_col < 5
    ORDER BY int_col DESC
    LIMIT 5
    UNION ALL
    SELECT float_col FROM test
    WHERE int_col < 5
    ORDER BY int_col DESC
    LIMIT 10
    ```
