Does it make a sense to remove ResourcePrefetchPredictorConfig from the
ResourcePrefetcherManager as well?

This will be merged into the policy part, that will need knowledge of the
configuration.

+  auto prefetcher = base::MakeUnique<ResourcePrefetcher>(
+      this, config_.max_prefetches_inflight_per_navigation,
+      config_.max_prefetches_inflight_per_host_per_navigation, main_frame_url,
+      urls);
   prefetcher->Start();
   prefetcher_map_[key] = std::move(prefetcher);
 }
