Remove drools-osgi-bundles: No one uses those (everyone uses the maven jars with osgi metadata directly) + their dependencies are broken + they randomly break jenkins + the tests have been replaced by (drools)-karaf-itest in the droolsjbpm-integration repo which are much more reliable
Remove the OsgiVersion complexity from the build scripts and the release procedure: we no longer need it thanks to Christiano's and Charles's changes.
Set release version: 6.0.0.Beta1
to version 6.0.0-SNAPSHOT
