// |clients| is a map of DownloadClient -> std::unique_ptr<Client>.  This
// represents all of the clients that are allowed to have requests made on
// their behalf.  This cannot be changed after startup.  Any existing requests
// no longer associated with a client will be cancelled.
// |storage_dir| is a path to where all the local storage will be.  This will
// hold the internal database as well as any temporary files on disk.  If this
// is an empty path, the service will not persist any information to disk and
// will act as an in-memory only service (this means no auto-retries after
// restarts, no files written on completion, etc.).
// |background_task_runner| will be used for all disk reads and writes.
