    Multi host DHCP networking and local DNS resolving
    
    Configure all dnsmasq instances to use the hosts file instead of the
    default local file '/etc/host' when the network is configured in
    'multi_host' mode.
    
    This hosts file contains all DNS entries of the network and it is
    replicated on all host where a 'nova-network' daemon is instantiated.
    There is a hosts file for each networks.
    
    It needs to add a new network API to update the host file on all
    network hosts.
    
    When a network host is called to (de)allocate a VM, it (de)allocate the
    instance fixed IP adress(es) on the concerned network host and when it's
    done, it calls all networks to update their DNS db entries if it's
    needed through a fanout cast.
