WIP: KUDU-1369. client: fail over scans to a new replica if current replica is out-of-date

If one replica doesn't have up-to-date enough data to service a snapshot scan,
the resulting error should cause the client to failover.

This is a WIP because the code's getting pretty hack in this area, and
we should devise a test case.
