Fix excessive Redis calls for new HSET/HMGET diffs cache
What does this MR do?
Before this change, we were submitting multiple HMGET
calls to Redis unnecessarily when reading or writing to the cache, reaching incredibly high timings when enabling the hset_redis_diff_caching
feature flag.
This MR fixes that by using a memoized method.
Closes #39133 (closed)
