    IMPALA-13219: test_rows_sent_counters is flaky due to CreateResultSetTime check
    
    The test_rows_sent_counters test expected CreateResultSetTime to be in
    the range of [2400, 2600] ms for
    'SELECT sleep(100) FROM functional.alltypes LIMIT 25'.
    
    However, as noted in 'man 2 nanosleep', even after a sleep completes,
    there can still be a delay before the CPU becomes free to execute the
    calling thread. On loaded test environments, this CPU scheduling delay
    accumulates across the 25 rows, causing create_result_ms to slightly
    exceed 2600ms.
    
    To deflake this test, this patch increases the upper limit of
    create_result_ms from 2600ms to 2800ms.
