    nuageinit: support fetching configuration on multiple iface
    
    On some environement a VM can be connected to multiple ifaces but only
    one will respond to dhcp and able to fetch the metadata.
    
    Launch the early dhclient on all available ifaces and as soon as one
    dhcp has successfully configured an iface, proceed with fetching the
    metadata.
