    Fix uuid passing in disable_isolated_metadata_proxy

    In DhcpAgent, when enable_isolated_metadata_proxy() spawns
    a metadata proxy agent for a network, it will pass router_id
    instead of network_id if metadata network is enabled and
    a router port is connected to this network.

    Later, MetadataDriver will register this uuid (i.e. router_id)
    with monitor for the new metadata proxy process.

    But when disable_isolated_metadata_proxy() destroys a metadata
    proxy agent for a network, it always passes network_id as the uuid.
    Thus MetadataDriver can not find the matching process. So the
    corresponding metadata proxy agent can not be destroyed.
