36c4da372b (VDB-570) Handle duplicate storage diffs
- If processing a new diff for a row that already exists in the DB,
  ignore the error without logging or queueing
- If processing a queued diff for a row that already exists, remove
  it from the queue

b036053937 Queue storage diffs if transformer execution fails
- For any error, not just if key isn't recognized
- Means we don't lose track of diffs on random ephemeral errors

2d684c5aec Extract storage diff fetching behind an interface
- Replaces directly reading from a CSV
- Simplifies testing
- Should hopefully make it easier to plug in other sources for storage
  diffs (e.g. differently formatted CSVs, JSON RPC, etc)
