Remote clients should avoid reading from remote storage servers if there is large version lag

In fearless setup, remote clients try to read data from remote storage servers. If there is "FutureVersion" error then it tries to fetch data from primary storage servers. In scenarios where the remote datacenter is down for a considerable amount of time and then comes back up, it would take some time for the remote storage servers to catch up. So remote clients should avoid reading from remote storage servers until they catch up.
