Fix odl-genius

Fix odl-genius

Multiple things done to clean up packaging:
- use properly-imported artifacts poms from upstream to eliminate
  properties
- add proper dependency on odl-serviceutils-listener to eliminate
  duplicate packaging
- eliminate unneeded explicit dependencies, they are pulled in as
  needed
- cloudscaler dependency on javax.annotation is optional, as it is
  not used in Karaf and should not be pulled into the feature
