Add temporary installer support for creating default filesystem
configuration for AIOs. This will create the following based on the
current AIO CentOS kickstart settings for large disks:
- Platform backup partition/filesystem
- Default physical volume and volume group for cgts-vg
- Logical volumes for log-lv and scratch-lv
- Format platform backup, log, and scratch filesystem as ext4
Test Plan (using 512G root disk):
- PASS: Build/Install ISO
- PASS: Observe correct partitions, physical volume, volume group,
logical volumes present after boot
- PASS: Reinstall ISO after successful install
Note: /etc/fstab is updated as a post-rootfs script in
base-bullseye.yaml
