Fix monitoring network policy to use component-prometheus

* Wildfly used the port 9990 for metrics, in Quarkus HTTP 8080 is used
* Rancher Monitoring is no longer in use and therefore being dropped
* component-prometheus is by default deployed in syn-infra-monitoring
* Label app=prometheus has been renamed to
  app.kubernetes.io/component=prometheus
* The keycloak label is keycloakx since the Quarkus migration
