Zitan Chen be41c61f22 Add a new option for BackupEngine to store table files under shared_checksum using DB session id in the backup filenames (#6997) ... Summary: `BackupableDBOptions::new_naming_for_backup_files` is added. This option is false by default. When it is true, backup table filenames under directory shared_checksum are of the form `<file_number>_<crc32c>_<db_session_id>.sst`. Note that when this option is true, it comes into effect only when both `share_files_with_checksum` and `share_table_files` are true. Three new test cases are added.
