'''This file is to do data-plane baseline test for
VM pair life-cycle events using netperf.
Testing steps are summarized below:
1. run_test load testcase configuration
2. Bottlenecks eliminates the environments limits/constraints
3. Bottlenecks tells Yardstick to prepare environment
4. Bottlenecks tells Yardstick to run test
3.1 to create stack
3.2 to install netperf
3.3 to send/forward packets for t2 seconds
3.4 record results and detroy stack
3.4 after every t1 seconds goto 3.1 and repeat the workflow
5. Bottlenecks collects testing results from Yardstick
6. Bottlenecks tells Yardstick to stop when time ends
or system fails the test
7. Bottlenecks sends testing data to bottlenecks-elk'''
