ospfv3: T5717: allow metric and metric-type on redistributed routes

Example:
vyos@vyos# set protocols ospfv3 redistribute bgp
Possible completions:
   metric               OSPF default metric
   metric-type          OSPF metric type for default routes (default: 2)
   route-map            Specify route-map name to use
