Add IxNextgen API for creating PPPoX configurations

New IxNextgen API allows to perform the following configurations on IxNetwork:
 - add topology
 - add device group to topology
 - add ethernet protocol layer to device group
 - add ipv4 protocol layer to device group
 - add pppox protocol layer to device group
