    METRON-1471: Migrate shuffle connections to local or shuffle

    ## Contributor Comments
    Currently, we use shuffle groupings when we do not want to group by field.  
We should, instead, use local or shuffle groupings.
    
    Manual tests should include ensuring data continues to flow as before.
