ResetStatus deletes snapshots for VAB.
When ResetStatus() is called, delete snapshots to free up space on
VAB devices.
On regular A/B, there is no need to cancel the update completely so that
the update may be resumed next time. However, on VAB devices, a
cancelled update should not occupy previously allocated space.
Test: manually call update_engine_client --cancel when an update is in progress, then
call update_engine_client --reset_status, then
call snapshotctl dump to check that snapshots are deleted.
Then, re-apply the update.
Test: manually kill update_engine when an update is in progress, then
call update_engine_client --reset_status, then
call snapshotctl dump to check that snapshots are deleted.
Then, re-apply the update.
Test: manually apply an update until UPDATED_NEED_REBOOT, then
call update_engine_client --reset_status, then
call snapshotctl dump to check that snapshots are deleted.
Then, re-apply the update.
