The Configuration Status page after the migration to JQuery UI requires a few improvements:
- The ServiceTracker used to track ConfigurationPrinter services should be closed on deactivation
- System Properties and core Threads tab have special treatment. It would make handling easier
if they would just be internal (non-service) Configuration Printer instances. As a consequence the
panels are not properly added in the correct sort order
- If multiple Configuration Printer services are registered with the same title, one instance will not
be properly added to the list.
