    Use db constraint to ensure mac address uniqueness

    Currently port mac address uniqueness per network is checked before Port
    db object create but without locking. It implies 2 port create requests
    can allocate the same mac address on a network if each request performs
    mac address uniqueness check before the other creates the Port db object.

    This change replaces the check by a db unique constraint on Port
    (network_id, mac_address).
