UDP-Encap: name counters for the stats segment
change the ADD api so that is returns the 'ID' that can be used
by the client to read the stats from the stats segment and to
delete the object. Previously a similar value used required
to be chosen by the client, now VPP allocates one (like it
does e.g. for interfaces)
