[FLINK-2098] Ensure checkpoints and element emission are in order
Before, it could happen that a streaming source would keep emitting
elements while a checkpoint is being performed. This can lead to
inconsistencies in the checkpoints with other operators.
This also adds a test that checks whether only one checkpoint is
executed at a time and the serial behaviour of checkpointing and
emission.
