    In IPv6 only search addresses in tentative if interface is UP

    During usage it was observed, in IPv6, that if a interface is with
    operational state in DOWN, it will take more time to leave the DAD
    state "tentative", if the system starts without carrier the flag
    remains until a carrier signal is provided.

    Since interfaces in DOWN are not affected by duplicated address
    in the network, this change adds a script to test this condition
    over active interfaces only.

    Test Plan:
    [PASS] remove the signal of an ethernet port that is configured and
            execute lock/unlock. Observe that there will be no puppet
            error in "wait-for-tentative".
