Keep the pool flag around so we can distinguish between a pool that
should maintain hashes for each chunk, and a missing one is a bug, vs
an overwrites pool where we rely on bluestore checksums for detecting
corruption.

This is based on a script that I've been using for a while for basic
smoke testing. The matrix has exploded with the addition of data-pool
and now it's primarily a data-pool test fixture that takes minutes to
run, so turning it into a workunit.
