Record iteration methods in JOIN_CACHE_BNL public

      Description

      This commit creates new public methods to iterate the join
      cache. This is useful for engine condition pushdown in
      remote storage engines. In addition to push the condition,
      we can also push data to match rows during JOIN.
      This avoids full table scan and hence full table read
      over the network.
