This commit automatically triggers the local restore after remote
subcloud installation during an auto-restore operation.
It also adds support for using a backup file initially stored on the
system controller by copying it to the miniboot.iso, which is then
transferred via kickstart to the subcloud [1].

Test Plan:
Before running the following tests, prestage the subcloud for install
and create two backups, one with --local-only and another without it.
01. PASS - Run a subcloud restore with --auto. Verify that the subcloud
is auto-restored with the backup stored inside the system
controller.
02. PASS - Run a subcloud restore with --auto and --local-only. Verify
that the subcloud is auto-restored with the local backup stored
inside the subcloud.
03. PASS - Run a subcloud restore with --auto and force a failure
during restore. Verify that the restore playbook detects the
failure correctly.
04. PASS - Copy the local platform backup file to
/opt/platform-backup/factory/<sw-version>/ and run a subcloud
restore with --factory. Verify that the subcloud is restored using
the backup stored in the factory directory.
05. PASS - After a subcloud is auto restored, verify that the
/opt/platform-backup/auto-restore directory is removed.
06. PASS - After a subcloud is auto restored, restart the subcloud and
verify that the dc-auto-restore systemd service is not triggered.
07. PASS - After a subcloud is auto restored, verify that the log file
/var/log/auto-restore.log exists and contains all the logged data
from the execute-restore.sh script and the restore playbook output.
08. PASS - Run the standard subcloud restore operation (without --auto
or --factory) and verify that it's still working.
09. PASS - Verify that the temporary directory and all staged files are
deleted after the subcloud install operation is complete.
