Introduce ip address monitor
In Juno, we used keepalived notifier scripts to report the local
state of an HA router's state. These have been found to be
unreliable. The proposed approach is to not use them altogether.
Instead, monitor the omnipresent VIP on the HA device - It is
only configured on the master instance. In order to do that,
we'll use the 'ip monitor address' wrapper introduced in this patch
to get address change events as they happen to avoid polling.
