Comment 9 for bug 1471568

It's common to modify/delete or recreate the default networks created by Fuel. Fuel should not try to recreate the net04 networks on a redeployment but leave the OpenStack resources as is.

@Vitaly Sedelnik: When we update from 9.0 to 9.1, we also execute redeployment, so in that case we may hit the same issue described here.
