    IMPALA-14171: Deflake TestQueryExecTimeLimit.test_exec_time_limit_long_plan
    
    The test expects a "SELECT..LIMIT 1" query on tpch.lineitem to finish in
    2s. This could be impacted by other concurrent tests when memory
    reservation is used up. This patch marks the test to run serially to
    avoid the impact from other tests.
