    SAMZA-1505: Fix CheckpointTool writing only one ssp per task

    Currently when using CheckpointTool to write checkpoints, it only writes a checkpoint
of a single ssp per task. By debugging the code, looks like the flatMap() on the checkpoint
of Optional tuple(taskname -> Map(ssp -> offset)) merges the results by key taskname.
This patch stores the results explicitly in a list and then groupBy() on it, which fixes the
problem.
