Make minicluster service classes public so they can be added to MiniCluster.
CDK-700. Start HiveServer2 in Hive service.
Remove main JAR shading. It causes problems when running the
minicluster in a webapp, since servlet and related classes are included.

The correct solution is to have another bundle for the CLI. See CDK-691.
Treat flume configuration as a resource if not found as a file.
