run download checksum verification in separate job pool
get, move, copy, sync: When -J or annex.jobs has enabled concurrency,
checksum verification uses a separate job pool than is used for
downloads, to keep bandwidth saturated.

Not yet done for upload checksum verification, but that only affects
remotes on local disks.
