v2 API Retry on 429 status_code if users are throttled?

[michaelbabyn]

Right now we Only retry on request errors with 5XX status code and use exponential backoff. But should we also retry for 429 status codes which users receive if they go over Plot.ly's throttling limit? Especially since calls to the image servers are now limited to 1/sec.

Sure, that sounds reasonable.
