Read OpLog support #22

Does the driver has support for reading the OpLog collection as the native driver?

You can certainly query and tail the oplog but the driver never exposed the oplogReplay since MongoDB Inc. have consistently made noises that it will go away.

With the restartable cursors the need for the oplogReplay is greatly diminished since you can persist the identity of a cursor and restart where you left off without the need to seek in the oplog at all.
