[CARBONDATA-2475] Support Modular Core for Materialized View DataMap for
query matching and rewriting
Currently carbon supports preaggregate datamap, which only supports
preaggregate on single table. To improve it, we can add join capability by
implementing Materialized View.
In carbon Materialized View, Modular Core provides the plan matcher and
rewrites the query with MV query.
