    Periodic update of DNS entries.
    
    The new DNS mechanism to resolve instance names on private network with
    multi hoste mode doesn't scale.
    This patch add the possibility to update the DNS entries periodically on
    each network host instead of fanout cast each time the DNS entries need
    to be updated.
    
    DocImpact: new config options
    Fixes LP bug #1086026
