Handle http status code 429 for retry after time given in response, and handle 503 service unavailable.

Hello. How would you like 503 service unavailable to be handled ?
Simple error print ?

@edvoinea it will be better if we can have configurable retry, Like user can feed some seconds and we can retry once.
