    Fix straggling uses of direct-to-database queries in nova-network

    There were a few remaining calls directly to the database module
    left in nova-network. These would fail because of the wedge we
    put in place specifically to catch this case. However, we don't
    test VlanManager in the gate, which means we didn't catch them
    until now.

    This required adding two more methods, one each to Network and
    NetworkList, but they are both extremely simple.
