Summary: Introduce an new option options.check_flush_compaction_key_order, by default set to true, which checks key order of flush and compaction, and fail the operation if the order is violated. Also did minor refactor hash checking code, which consolidates the hashing logic to a vlidation class, where the key ordering logic is added. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7467 Test Plan: Add unit tests to validate the check can catch reordering in flush and compaction, and can be properly disabled.
