update_engine: Scaled DLC installation

Expose scaled DLC installation, which will fetch DLC images/payloads
from Bandaid(+Lorry) URL paths with DLC slotting.

Lorry is used as a fallback/backup of Bandaid URIs.

When DLCs are installed, the specific offset and SHA256 hash are hard
requirement to match that of rootfs before further downstreams use with
device mapper features. (This step should save downstream folks from
requiring secondary verification and reduce repeated hashings)
