Review comment:
Here, before validating the new routers, we are destroying the old ones. If
the new routers don't come up properly, we won't have old routers to roll back.

> restartnetwork with cleanup should not update/restart both routers at once

> Issue Type: Improvement
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Reporter: Wei Zhou
> Assignee: Wei Zhou
> Priority: Major
>
> for now, restartnetwork with cleanup will stop both RVRs at first, then start
> two new RVRs.
> to reduce the downtime of network, we'd better restart the RVRs one by one.
