add network info to topology

we need to know which network each port is connected to
so we can find VLAN or VXLAN ID.

To do this we implement a new method for Contexts,
Context.get_network().  This method is similar to
Context.get_server(), it searches for a given
network name in all the contexts.

From this we generate a context_cfg["networks"]
dict that stores all the network info for the nodes
in the scenario.

Then when we generate the topology for VNFD, we can
lookup a given network by the vld_id and get the
network_type, segmentation_id, etc.

Then if we need to for example generated
traffic on a given VLAN or VXLAN, we have this
info available.

Define default nd_route_tbl for ACL VNF
we need default empty nd_route_tbl for IPv6 route.
