Have the object server stick a header on the conflict response to SYNC when a newer file exists. This allows the replicator to remove local files that are out of date, and maybe later it can be smart enough to pull down the newer file on non-handoff replication. Also adds quarantine for file audit errors on replicate. Change-Id: If0b83f4899e89a43c5f732008848b62165c355df
