This commit creates an upgrade script that runs on 'delete'
action only for AIO-SX systems only, and its main goal is to
delete existing LVM snapshots at the end of the deployment
process, in both forward and rollback paths.
Test Plan
PASS: run script in AIO-SX with existing snapshots, verify
snapshots are deleted and logs are logged as expected
and script return success
PASS: run script in AIO-SX with no snapshots, verify script
logs that there are no snapshots to be deleted
PASS: run script in system other than AIO-SX, verify script
logs 'nothing to do'
PASS: run script with action != 'delete' and verify script
logs 'nothing to do'
