Summary: 1. Extend FlushJobInfo and CompactionJobInfo with information about the blob files generated by flush/compaction jobs. This PR add two structures BlobFileInfo and BlobFileGarbageInfo that contains the required information of blob files. 2. Notify the creation and deletion of blob files through OnBlobFileCreationStarted, OnBlobFileCreated, and OnBlobFileDeleted. 3. Test OnFile*Finish operations notifications with Blob Files. 4. Log the blob file creation/deletion events through EventLogger in Log file.
