/// What's the setting_name_prefix, and why do we need it?
/// There are (at least) two config sections where s3 settings can be specified:
/// * settings for s3 disk (clickhouse/storage_configuration/disks)
/// * settings for s3 storage (clickhouse/s3), which are also used for backups
/// Even though settings are the same, in case of s3 disk they are prefixed with "s3_"
/// ("s3_max_single_part_upload_size"), but in case of s3 storage they are not
/// ( "max_single_part_upload_size"). Why this happened is a complete mystery to me.
