ISSUE-2725: Sometimes bin/bookkeeper localbookie does not work from source code

[sijie]

Original Issue: apache#2725

---

When you run the command bin/bookkeeper localbookie 1 from the source code it may happen that it does not work and finished with
Error: Could not find or load main class org.apache.bookkeeper.util.LocalBookKeeper

This is because the find_module_jar function finds these files as main BK server jar:

/PATH-TO-CODE/bookkeeper-server/target/bookkeeper-server-4.14.1-javadoc.jar
/PATH-TO-CODE/bookkeeper-server/target/bookkeeper-server-4.14.1-sources.jar
/PATH-TO-CODE/bookkeeper-server/target/bookkeeper-server-4.14.1-tests.jar

To Reproduce

Run

mvn clean install -DskipTests
bin/bookkeeper localbookie 1

Suggested fix
Enhance find_module_jar in order to skip additional artifacts or use some mvn plugin to get the path of the jar file
