HTTPClient now supports a retries argument. It will reissue requests for any 5xx or socket (400 with n/a) errors. This retry loop was "inspired" by swiftclient's loop. It reauths one extra time if necessary. It uses backoff times of 1, 2, 4... seconds. The default is 0 retries. It is also exposed to the shell as well with a --retries arg.
