title: command to clean apache-karaf cache
body: <p>Is there any command to clean the karaf container?
  ie) I am trying to create a bundle and installing the bundle multiple times in apache-karaf-2.3.10. After certain number of tries karaf is not performing as expected. Sometimes names are not appearing instead absolute path of the bundle appears. So i am expecting a karaf shell command to clean the data cache folder so that karaf goes back to original state(kind of factory reset).</p>
