Konstantina Chremmou f8117cd4f5 CA-114482: Changed workflow of retrieving updates: the list of published updates
is downloaded and stored every time an update is performed (if manual all updates
are downloaded, if automatic only as per the user's choices). If there are available
updates, update alerts are generated if there are connected hosts and disappear
when the hosts are disconnected.
