Subject: [PATCH] Wipe all LVs during kickstart

Backup and Restore are not completing because the manifest is
not applied when trying drbd-cephmon turns primary,
It is occurring because the LVs are not being wiped before
being removed, so some garbage is impacting drbd-cephmon
turns primary and causes the manifest fails to not be applied.

To ensure that drbd-cephmon turns primary on first unlock,
LVs will be wiped before recreating them during kickstart
procedure.

Test Plan:
PASS: Backup and restore on AIO-DX
PASS: Install AIO-SX over the previous installation without
wiping the disks and checking the install.log to verify
if the disks are wiped during kickstart.
PASS: Install AIO-DX, reinstall Controller-1, and checking the
install.log to verify if the disks were wiped during kickstart.

Closes-Bug: #2031542
