Originally I had hoped to feature-flag the changes to support redis hash
caching, as they seemed small, but of course those changes expanded and
expanded until it became clear it really needed to be extracted into a
new class with a parallel API to keep it clean. h/t to @oswaldo for
pointing out when we'd crossed that threshold!

HSET allows us to use a Redis hash, so we can store the combined diffs
for a given merge request rev in a single key _and_ access individual
file diffs as needed.
