reconciler: update logging call

All (non error) logs have the same verbosity; it would be interesting
to see the reconciled IPs by default, as such I'm bumping this
particular logging call to `verbose`.
That enables users to `kubectl logs <reconciler-pod-name` and see which
IP addresses got reconciled.

The below calls would be bumped to `verbose`.
