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. Signed-off-by: Francesco Pantano <fpantano@redhat.com> (cherry picked from commit 4416516)
