55baa3d955 Add an option to table_reader_bench to access the table from DB And Iterating non-existing prefix case.
Summary: This patch adds an option to table_reader_bench that queries run against DB level (which has one table). It is useful if user wants to see the extra costs DB level introduces.

Test Plan: Run the benchmark with and without the new parameter
