    Update instance network info cache to include vif_type.
    
    vif_type is a new param in legacy_nw_info added in grizzly, and when upgrading
    from folsom to grizzly, the existing instance's network info cache in the db doesn't
    contain this param, which is needed by vif driver to plug vif to instance. Nova
    compute will try to plug the vif when it starts the instance, so we need to update
    the existing instance's network info cache before pluging instance's VIF.
    
    fix bug #1152426

Title:
  vif_type not in  existed instances info_cache cause upgrade from
  folsom to grizzly fails

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  when  upgrade from folsom to grizzly,  nova-compute can't  starts
  because vif_type is None,  vif_type is  added to networkinfo model in
  grizzly, so when  upgrade a  folsom env to grizzly,  existing
  instances's  info_cache need to  update to  set this param.
