From: David Ahern <redacted> Add ipv4 and ipv6 test cases with an invalid metrics option causing ip_metrics_convert to fail. Tests clean up path during route add. Also, add nodad to to ipv6 address add. When running ipv6_route_metrics directly seeing an occasional failure on the "Using route with mtu metric" test case.
