> We should extend the BSPJob to let the user set the checkpoint intervals.
> bq.  job.setCheckpointInterval(5);
> This method should put the parameter into the configuration of the job with a meaningful
key, e.G. "bsp.checkpoint.interval".
> In the BSPPeerImpl we should check if this interval has been reached and make the checkpointing
accordingly.
> Checkpointing gets called in BSPPeerImpl#sync(), there is already a condition which checks
if checkpointing is enabled.
> Plus points:
> If you can provide an additional method in BSPJob that let's the user enable or disable
checkpointing. Hint: Configuration key is: "bsp.checkpoint.enabled".
