      Description

      Add a NestedFieldsProjectableTableSource interface for some TableSource implementation that support nesting projection push-down.
      The interface could look as follows

      def trait NestedFieldsProjectableTableSource {
        def projectNestedFields(fields: Array[String]): NestedFieldsProjectableTableSource[T]
      }
      

      This interface works together with ProjectableTableSource
