Implement the workflow of compute qpi

Local test is ok.
The result will be written to report.json.

usage: runner.py [-h] -d DEST -b BENCHMARK

optional arguments:
  -d DEST, --dest DEST  the destination where results will be stored.
  -b BENCHMARK, --benchmark BENCHMARK
                        the benchmark you want to execute.
