* Proactively clean up idempotency ids for successful commits
This change also includes some minor changes from my branch working on
an idempotency ids cleaner, that I'd like to get merged sooner rather
than later.

- Checking idempotencyIdsExpiredVersion in determineCommitStatus
- Some testing QOL changes
* Factor out decodeIdempotencyKey logic
* Fix formatting
* Update flow/include/flow/error_definitions.h
