Summary: The patch adds a log message to `BlobFileBuilder` that is logged upon generating a blob file, similarly to how we log the generation of table files during flush and compaction. The log message contains the column family name, job id, blob file number, and the number and total size of blobs in the new file. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7324 Test Plan: Ran `make check` and checked the actual log messages using a custom `db_bench`.
