Changes to base project

1. Remove files to the minimum

2. Log something to expose the issue

   • For this example we use the default logger org.jboss.logging.Logger
   • Quarkus uses JBoss Log Manager and the JBoss Logging facade.

3. Create a load test

   • For this example we used jmeter-java-dsl
   • check BasicLoadTest.java
