Re: [keycloak-dev] Operational monitoring of Keycloak server

Ok so we add one that just returns OK or ERROR which doesn't require authentication, but then we add another that can return more details, including stats and what the error is.

For full health we should check all external services that are used (db, identity providers and user federation providers). Cluster sync will depend on what Infinispan exposes, but I imagine they'll have the required details avail.
