Subject: [PATCH] Config the monitoring stack components api urls using a VIP

When dashboard_frontend_vip is provided, all the services should be
configured using the related VIP. A new VIP variable is added for
both prometheus and alertmanager: we're already able to properly
config the grafana vip using dashboard_frontend_vip variable.
This change adds the same variable for both prometheus and
alertmanager.
