QA:Testcase partitioning webui custom with swap

Associated release criterion
This test case is associated with the Fedora_42_Final_Release_Criteria#disk-layouts release criterion. If you are doing release validation testing, a failure of this test case may be a breach of that release criterion. If so, please file a bug and nominate it as blocking the appropriate milestone, using the blocker bug nomination page.

Description

An installation using webui's 'storage editor' and including a disk-based swap partition (not included by default since Fedora 33).

Setup

1. Prepare a test system with a working, supported storage device of sufficient size for a Fedora install, and a Fedora installation medium that uses the webui-based installer - e.g. Fedora Workstation live, on Fedora 42 and above.

How to test

1. Boot the webui-based installer using any available means, e.g. Fedora Workstation live on Fedora 42+.
2. Proceed to the installer's "Installation method" screen, making sensible choices.
3. Ensure only the single target device you prepared is selected as the installation target disk.
4. Click the 'kebab menu' (the three white dots in a vertical line) at the top-right corner, and click "Launch storage editor". Click "Launch storage editor" again to confirm.
5. On the Storage screen, delete all existing partitions (if any), using the kebab menu for each partition.
6. Create any necessary bootloader partitions (e.g. EFI System Partition for UEFI installs, BIOS Boot partition for BIOS installs onto a GPT disk, PReP boot partition for PowerPC installs).
7. Create a /boot partition and set the filesystem type to btrfs or xfs.
8. Create a partition with type Swap and set the size to 2G.
9. Create a root partition and set the filesystem type to btrfs or xfs.
10. Complete the installation process, making sensible selections for all other installer options.
11. Boot the installed system.

Expected Results

1. The expected partition layout should be created on the target device(s).
2. The install process should complete successfully and the installed system should boot as expected.
3. The installation should complete successfully.
4. The disk-based swap partition should be active (you can check /proc/swaps or the output of swapon --show).
