Add a boolean to DistributedPlanLogic that will indicate that the shards part of the pipeline should be broadcast to all primaries and secondaries in the cluster.
Rather than calling establishShardCursors() within dispatchShardPipeline(), establish cursors on all nodes in the cluster using the AsyncMulticaster similarly to how sessions are killed on all nodes.

This ticket will also modify $_internalSplitPipeline to add an option that forces a pipeline to split and broadcast to all nodes for testing purposes.
