Comment 2 for bug 1674614

In our real production, we need to turn off the networks nodes where LBaaS agents run. In such scenario, we need to migrate LBaaS instance from one network node to another, just like L3 routers. In https://bugs.launchpad.net/octavia/+bug/1565511 , loadbalancers will be rescheduled from one network node to another when network node goes offline. I think that this is a passive method. We need a positive method, isn't it?
