Comment 4 for bug 1495430

I was wondering if I can modify
    def delete_vip(self, vip):
        #self.undeploy_instance(vip['pool_id'])
        self.undeploy_instance(vip['pool_id'],delete_namespace=True)
# is the old code.
Why we don't do this in delete_vip? create_vip creates namespace and plugs it as well.
