Introducing Generic framework to do pre-deployment VNF & Network service testing

This patch introduces the framework which is aligned with ETSI-TST001

This patch adds:
1. NetworkServiceTestCase introduces following functions
      --> setup
            --> Verify if infrastructure mapping can meet topology
            --> Load VNF models
            --> Fill traffic profile with information from topology
            --> Provision VNFs
            --> Run experiment (traffic)
      --> run -> Yardstick calls run() at intervals defined in the yaml
                 and produces timestamped samples
      --> teardown --> Stop  VNFs

2. TrafficProfile is a generic class to get traffic profile for a given
   testcase and select the traffic generator for testcase.

3. QueueFileWrapper is a class to send/recive cmds to vnf

4. GenericVNF is a generic class to instantiate VNF

5. GenericTrafficGen is a generic class to run/listen/verify traffic.
