Develop a new test for system updates via Cockpit.
    
    * server-cockpit-updates tests that Cockpit can be used to update the system.
    * server-cockpit-autoupdate tests that users can use dnf-automatic for system
    updates.
    * cockpit functions were removed from utils.pm and put into an extra library
    for cockpit - cockpit.pm which all cockpit tests are now using.
