Review Comment:
The `replica_bulk_loader::clear_bulk_load_states` function executes
`_metadata.files.clear()` and `cleanup_download_tasks()`.
Since `cleanup_download_tasks()` does not halt the ongoing
`replica_bulk_loader::download_sst_file`, there's a need for locking access to
`_metadata.files` within `download_sst_file` to prevent concurrency issues.
