As part of an effort to minimize the time to recover an
AIO-SX system in case of a boot failure during an upgrade,
this commit creates a service that executes during the boot
sequence and:
1. Verifies if system is booted from the rollback deployment
2. Checks if current ostree commit-id matches from-release commit-id
3. If 1 and 2 are met, attempts to restore the LVM snapshots
The delete_older_deployments function is changed as well, to
find the active deployment (in this case not the first in the
ostree admin status output) and only allow removing deployments
with indexes greater than the active.
Test Plan
PASS: AIO-SX install/bootstrap/unlock
PASS: AIO-SX upgrade stx-10 -> stx-11 using LVM snapshots
feature, force boot failure by using the grub flag, verify
the service executes and restore the snapshots
