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. JIRA: YARDSTICK-483 Change-Id: Ic453c917d34dcb508a7f3afb459011da85f6402e Signed-off-by: Deepak S <deepak.s@linux.intel.com>
