QA:Testcase Preupgrade cli

Description

This case tests upgrading a Fedora system from the stable release (e.g. Fedora 41) to the branched release (Fedora 42) using PreUpgrade-cli.

How to test

1. Perform an installation of the stable release (e.g. Fedora 41) with default partitioning (no less than 500MB for /boot).
2. Install the newest available version of preupgrade and python-urlgrabber
3. Run preupgrade-cli followed with a valid entry name from a command prompt, for example:

   preupgrade-cli "Fedora 14 (Laughlin)"

   . You can also run preupgrade-cli first to check the available valid entries.
4. When the process completes, reboot the system.
5. The system should perform the upgrade, and reboot into the new system automatically.
6. Log in to upgraded system, run some system applications.

Expected Results

1. The preupgrade utility will run to completion, without error
2. The upgrade should complete and reboot without user assistance.
3. The system should be upgraded to new version without error.
4. The executed applications should display and work correctly.
