Overview

Retry strategy for exponential backoffs

This will rerun an HTTP call up to max_tries times. Each retry will be delayed. The delay will have an exponential backoff that makes each delay about twice as long as the previous delay. The delay will also have a random jitter added to avoid overloading the server from many clients retrying simultaneously.
