    Unskip and Add timeout method to dns check scenario
    
    In test_subnet_details, Tempest checks the effect of alternative dns
    server which is updated just before the check.
    However, sometimes the check failed because the update could not make
    it before the check. This reason is not concrete yet, but this problem
    happens three times in 60 minutes now.
    So we need to solve this problem soon for smooth development, and this
    patch adds timeout method for alternative dns part.
