* Update the router (holding RouterInfo objects) with current data
on update / sync. Since the sync method should reconcile out of
any state, we need to update the RouterInfo we store locally in
the driver to ensure we have not missed e.g. a ha_state_change.
* Consistently use RouterInfo instead of some mix of dict and Router
and RouterInfo.
* Ensure NAT rules are current by using a tag to clean them all and
then re-create the currently required rules before applying them via
iptables manager. This ensures there are no dangling rules or duplicates.
