  Allow users to enable/disable messages from the UDisks2 backend to aid
  debugging issues seen only in specific configurations.

  some further refinement.

  QT_LOGGING_RULES="org.kde.solid.*.debug=false" ./bin/solid-hardware5 listen
  QT_LOGGING_RULES="org.kde.solid.*.debug=true" ./bin/solid-hardware5 listen
  Plug/unplug USB storage device
  
  -> first two invocations show same output as before
  -> third invocation shows additional output, added/lost interfaces
