Levi Tamasi 583c6953d8 Move out valid blobs from the oldest blob files during compaction (#6121) ... Summary: The patch adds logic that relocates live blobs from the oldest N non-TTL blob files as they are encountered during compaction (assuming the BlobDB configuration option `enable_garbage_collection` is `true`), where N is defined as the number of immutable non-TTL blob files multiplied by the value of a new BlobDB configuration option called `garbage_collection_cutoff`. (The default value of this parameter is 0.25, that is, by default the valid blobs residing in the oldest 25% of immutable non-TTL blob files are relocated.) Pull Request resolved: https://github.com/facebook/rocksdb/pull/6121 Test Plan: Added unit test and tested using the BlobDB mode of `db_bench`.
