Deploy 1 VNF 1 PoP about son-tests

[DarioValocchi]

The test should be end-to-end in terms of platform. The request should be triggered whether from a mocked BSS or through a relevant GUI testing library.
In terms of infrastructure we should have two VMs or endpoint which are used to generate and receive traffic respectively. These could be activated by Jenkins and their flow could be steered through the service when the NS is deployed. Another query from Jenkins to one of this VMs could verify that the traffic has been steered through the service and that the service is working.
For this purpose we need:

• Two VMs with a REST interface to trigger the traffic generation/reception and to gather logs
• A NS composed basically of L2 bridges that just forward the traffic.
