 * Test to ensure that (dump/restore/export/import/oplog) works with a replica set connection string

 * 8. Import the collection.
 * 9. Add data to the oplog.rs collection.
 * 10. Ensure that the document doesn't exist yet.
 * 11. Now play the mongooplog tool.
 * 12. Make sure that the oplog was played
