Red Hat build of Keycloak version 22 has just been GAd, so we should start exploring the implications of replacing RHSSO in our MTA distributions. Red Hat build of Keycloak startup time and resources consumption is way lower than RHSSO given it has been implemented using Quarkus instead of EAP. This is really convenient for MTA, because as of today most of our resources footprint came from RHSSO.

The tool is managed with a brand new operator, so I guess there will be some differences that we'll need to address.
