debian: initramfs-ostree - Initial AIO partition/format support

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 Story: 2009101 Task: 44398 Signed-off-by: Robert Church <robert.church@windriver.com> Change-Id: I6fb3f5bcd26f9035327fb614a34b8fc35ea64362

+Subject: [PATCH 3/3] Add lvm2 package to initramfs
+
+LVM will be used to set up the minimal StarlingX volume group. Include
+the package in the Depends list so that vgcreate, pvcreate, lvcreate
+commands are available for provisioning.

+Subject: Prevent auto-expansion of fluxdata partition
+
+Set VSZ=20480 to prevent the fluxdata parition from expanding to fill
+all free space on the root disk.
+
+For an AIO we want to provide free space for various customer driven
+provisioning scenarios.
