[keycloak-dev] Keycloak metrics with Prometheus

Hi, We're working on an Ansible Playbook Bundle for Keycloak, for the Ansible Service Broker [0]. As part of a cohesive Mobile backend solution on OpenShift, we're adding prometheus metrics endpoints to our own (mobile specific) services, and have had some success with adding a metrics endpoint to Keycloak. However, we're not convinced the approach for adding the metrics endpoint is the best approach. The first approach used the jboss/keycloak-openshift image as a base image, then added in the necessary parts (jar file & config), producing a new image. I'm not a fan of this approach as it means we'll have to maintain the new image, keeping it up to date as the keycloak-openshift image gets updated. The second approach (PR in [1]), also uses the jboss/keycloak-openshift image, but copies the JAR file at APB provision time into a mounted Persistent Volume in the keycloak-openshift running container. This approach addresses the image maintenance issue, but feels a bit hacky. A couple of questions: * Do you have any thoughts on either of the appraoches so far * Would it make sense for us to create a PR for keycloak upstream that adds the necessary bits to expose a prometheus metrics endpoint. This would be disabled by default, and enabled based on an env var. Any thoughts or help are welcome.
