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.
