API Rate limiting should return 429 not 413

[Phil Day]

Currently the rate limiting code returns 413 (request too large) - it would be better if it returned 429 (too many requests)

Recording so it can be fixed as part of V3 API

[Christopher Yeoh (cyeoh-0)]

Looks like the current code is returning 403 not 413, but agree it should be 429
