    The 2.70 compute API microversion exposes virtual device tags for volume
    attachments and virtual interfaces (ports). A ``tag`` parameter is added
    to the response body for the following APIs:

    **Volumes**

    * GET /servers/{server_id}/os-volume_attachments (list)
    * GET /servers/{server_id}/os-volume_attachments/{volume_id} (show)
    * POST /servers/{server_id}/os-volume_attachments (attach)

    **Ports**

    * GET /servers/{server_id}/os-interface (list)
    * GET /servers/{server_id}/os-interface/{port_id} (show)
    * POST /servers/{server_id}/os-interface (attach)
