Don't allow renaming to an existing instance
Even if the target instance is down or we are not checking for IP conflicts
changing an instance name to a new one which is already in the cluster is
doomed to fail, because in a lot of places (among which figures the mind of
most users/admins) instance names are assumed to be unique.
