Subject: [PATCH] core: detect route-metric when creating nm-generated-assumed
connection
When generating a connection to assume it, also record the route-metric.
Do that by looking at the metric of the (best) default-route.
This is especially important since d51975ed921a5876b76e081b8f3df4e2ca1f1ca9.
Now NM would also manage the default-route for assumed connections.
So the generated assumed connection would have a route metric based on
the device type, which might differ from the external configuration.
This caused NM to replace the externally configured default-route.

(cherry picked from commit bc75cd53a8c5ba525016bfddc1644be59a45ed41)
