SERVER-17151 ConfigCoordinator should not call fsync
This is expensive to do, especially with WiredTiger and is not a
deterministic check. This change replaces it with something cheaper, but
has the same outcome - validates that previous writes were successfully
journaled, which is an approximate predictor that subsequent writes have
high chance of succeeding.
