* Initial rate limiting * Move rate limiting to client API * Update rate limits to hopefully be self-cleaning * Use X-Forwarded-For, add comments * Reduce rate limit threshold * Tweak interval * Configurable backoff * Review comments, set cleanup interval to 30 seconds * Allow generate-config to produce sane CI config * Fix Complement dockerfile
