Alistair Coles b9ae377eab Check for change before container replicator updates db
As described in the related bug report, unnecessary updates
to the container db during replication can impact object
object GET performance in certain circumstances.

This patch changes swift/container/replicator.py so that
calls to merge_timestamps and update_reconciler_sync
are conditional on values having actually changed.
