Generate dynamic wrk/wrk2 requests

order-query.lua

--[[
  This is an example of a wrk/wrk2 script to dynamically generate a range of GET requests for load testing.
  you can run it by tying something similar to the following

  ./wrk -t15 -c 15 -d 600s -R1 -s order-query.lua http://localhost:8080

  NOTE: Noticed that the requests are dynamically generated once, given to all the threads
        i.e you see request-a t times, then request-b t times.
        Ideally i'd like each thread to send a dynamically generated request for each request,
        What I see now is the group of threads getting a dynamically generated request.
