Gets and sets the property Marker. Use this parameter when paginating results to indicate
            where to begin in your list of invalidation batches.    Because the results are returned
            in decreasing order from most recent to oldest, the most recent results are on the
            first page, the second page will contain earlier results, and so on.    To get the
            next page of results, set the Marker to the value of the NextMarker from the current
            page's response.    This value is the same as the ID of the last invalidation batch
            on that page.
