elasticsearch data is not stored under target/esdata if -Des.path is not set

If a developer does not specify the -Des.path when starting tomcat with the cargo.run profile, then the elasticsearch data should be stored in the target folder just like the repository data. That way all elasticsearch data will be deleted when running mvn clean.

Currently the elasticsearch data is stored in esdata on the root folder of gogreen enterprise, which does not get deleted when running mvn clean.
