This change removes the localOrShuffleGrouping partitioning used when building the Storm topology. This is relevant when your DataSource spouts do not have the same number of executors as the FilterBolts, causing skew.
localOrShuffleGrouping would prefer local executors but Bullet requires equal load on each FilterBolt since all of them run all of the queries simultaneously. Skew is not nice and reduces our overall scalability.
