    Description

      This has the following benefits:

      1. Simplifies the query execution stage API.
      2. Eliminates the complexity of having both PlanStage::StageState::IS_EOF and PlanStage::isEOF.
      3. Brings the stage interface in line with the style we are moving towards with the storage layer's SortedDataInterface::Cursor.
