With the new version2.5 i. e. the device table in CA-PC has a new feature
"Manage Life Cyyle" to retire/unretire items. For the administration process
another feature is needed "Delete item" so you can delete a retired item directly.
In addition to the GUI delete support a similar script to the already existing script /opt/IMDataAggregator/scripts/remove_retired_items.sh is needed which removes
the items with the "Life Cycle" attribute set.
