Enable github action to run server modules MasterTestSuite

[StefanSchubert]

This seems to be a bit tricky, as because of relying on eclipselink we need to provide a link into mavens build repository, see servers pom.xml

                   <jvmArguments>
                        -javaagent:${settings.localRepository}/org/springframework/spring-instrument/${spring.instrument.version}/spring-instrument-${spring.instrument.version}.jar
                    </jvmArguments>

for the git runner we may use ~/.m2/ but then again it wouldn't match my local repository setup.
Hm....working with maven profile here?

Before solving the jvmArgument problem. Currently the MasterTestSuite runs from IDE via JUnit but not via maven surefire and mvn test !? So this needs to be solved first.

Working now. Problem was autodetection of the test provider junit4.x. So I configured it manually.
