Add a check for boundary rules for QUERY (tornado)

    QUERY requires that the request variable for number of queries be
    bound between 1 and 500; anything less than 1 should result in 1
    result and anything more than 500 should result in 500.

    If the test does not clamp the request variable as such, then it
    fails validation.
