[FLINK-909] Additional superstep barrier
This change introduces a new additional barrier at the end of a superstep
in iterations. It prevents the execution of an extra iteration at termination
and therby fixes[FLINK-909].
This pull request depends on [FLINK-951] and uses the old package names,
because [FLINK-951] was not merged yet.
