As a temporary measure, we've added ratelimiting on the gRPC endpoint for pd, via Traefik middleware. We plan to add similar ratelimiting functionality to pd itself, so that solo node operators can benefit from limited DoS protection. For now, we add this so that a subsequent CI deploy (e.g. #3784) doesn't remove the protection that's currently live.
