IBM example for ~2010 Java EE -> 2021 CloudNative Quarkus

See: https://github.com/IBM/application-modernization-javaee-quarkus
```

Application Modernization - From Java EE in 2010 to Cloud-Native in 2021
This sample demonstrates how to modernize 10+ year-old Java EE applications with cloud-native technologies and the modern Java runtimes Quarkus and Open Liberty. The modernized application is deployed to and operated with OpenShift, the enterprise distribution of Kubernetes.
```

Start by reviewing the linked IBM application-modernization-javaee-quarkus project and comparing it with the existing examples in this repository. Clarify which parts of the Java EE-to-cloud-native example should be added here and what deployment or documentation expectations apply; the work is done when the agreed example is incorporated and its required validation is complete.
