TestStream in streaming Flink Runner

Very cool.
One of the things that TestStream needs to ensure determinism is the notion
of quiescence, that is between each event one needs to ensure that the
downstream elements and watermarks are processed as completely as possible.
Is this guaranteed by the checkpoint lock? If so, it's worth at least a
couple of comments.
