RoundTrip will retry a request if it receives REFUSED_STREAM. To guard against servers that use REFUSED_STREAM to encourage rate limiting, or servers that return REFUSED_STREAM deterministically for some requests, we retry after an exponential backoff and we cap the number of retries. The exponential backoff starts on the second retry, with a backoff sequence of 1s, 2s, 4s, etc, with 10% random jitter. The retry cap was set to 6, somewhat arbitrarily. Rationale: this is what Firefox does.
