    Update network metadata type field for IPv6

    Currently it is not possible to decide from looking at the network
    metadata whether an IPv6 subnet is using slaac, dhcpv6-stateless or
    dhcpv6-stateful.

    So we add ipv6_address_mode information into the subnet metadata when
    it is available and use that to construct the subnet type.

    As a result, the type for a subnet with mode SLAAC will be "ipv6_slaac"
    instead of "ipv6_dhcp" and similarly for the other available modes.
