NP: use of Verification instead of Validation other places, rename to maintain consistent terminology

This could use a retry since it doesnt provide any metrics or anything to notify and we expect S3 puts to fail sometimes.

Added retries. We can metrics implicitly when we centralize validation and include these in the checks.
IMO we can justify stacking a bet here because this is meant as a fallback rather than the main mechanism to get these data.

This persists an alternative location for backup metadata in S3 in case of unavailability of the primary source of truth. Tests are in progress and will be added in a follow-up commit. I have confirmed it WAI in practice.
