    DRILL-5065 - Optimize count( * ) queries on MapR-DB JSON Tables

    In MapR-DB v5.2.0, we enabled '_id' only projection for JSON tables.
    Hence, we can now optimize the following queries:
    a. count(*) by projecting only the '_id' column.
    b. '_id' only projections, including count(_id)
    
    Change the format plugin config parameter name.
