Pass proper VIPs on Standalone

With HA being the default we should now specify the VIPs as well.
This way pacemaker will create the separate VIP and haproxy will listen
to it and we won't have both haproxy and the service itself listening to
the same port on the same IP.

Note: that we tried to make this work without creating a VIP at all and
having haproxy's backend services listen to localhost only and leave
haproxy to listen on the standalone IP, but this quickly became
impossible to make it work due to how things are coded in a number
of places (bootstrap hostname checks, pacemaker properties,etc.)
