    add Previous link to Admin > Images table

    The Glance API supports a sort direction which we can use to paginate back

    The Prev href tag contains a marker id of the first item in the table.
    When clicked, a GET API call is made, passing in this marker and the sort_dir='asc'
    This will return the previous page's data. Then we have to re-sort the data because
    it is ordered backwards. We use the default sort_key='created_by' for this.

    Once the patch #1252649 is restored, we can add the same behavior to Project > Images.

    If we are able to get the consistency across the APIs to include the sort_dir, then we can
    bring Prev to the other project tables as well. There are some blueprints to enhance
    API capabilities in this area.
