* internal retry capacity and slowly roll off from retry attempts until requests begin
* to succeed again. At that point the retry capacity pool will begin to refill and
* retries will once again be permitted

*
* In situations where retries have been throttled this feature will effectively result in
* fail-fast behavior from the client. Because retries are circumvented exceptions will
* be immediately returned to the caller if the initial request is unsuccessful. This
* will result in a greater number of exceptions being returned up front but prevents
