Increase backoff factor to 1.7 (from 1.5) for non-poll RPCs
Why?
The current backoff factor causes clients using the Core SDK to exhaust their retries within 6.011 to 8.966 seconds, depending on random jitter. We want to ensure that all clients keep retrying for at least 10 seconds. With the new backoff factor, retries will not be exhausted until 11.878 to 17.767 seconds after the initial failure.
