[NEW] benchmarks/py-locust: Python utility for doing distributed load tests

  Locust is an easy-to-use, distributed, user load testing tool. It is
  intended for load-testing web sites (or other systems) and figuring out
  how many concurrent users a system can handle.

  The behavior of each locust (or test user if you will) is defined by you
  and the swarming process is monitored from a web UI in real-time. This
  will help you battle test and identify bottlenecks in your code before
  letting real users in.
