Only a very limited featureset of the route-maps is implemented here,
only the stuff needed by the fabrics. Once standalone route-maps will
make it into pve, we will build these out and maybe rework them a
little.
We need the RouteMaps for the Fabrics, because otherwise, the routes
between to the route-ids will be distibuted, but won't be pingable,
because because the source address is wrong. By rewriting the source we
guarantee that a ping will always find it's way back to the source
router-id.
