features should come from jclouds/jclouds only?

I'm trying to update the feature.xml file in jclouds-karaf and I've notice that there are feature that reference bundles coming from `mvn:org.apache.jclouds.labs`

As per the nature of jclouds-labs project, some providers may also never be promoted so I'm not sure jclouds-karaf should reference them. This make the jclouds-karaf maintenance complicated IMHO
