urls.py changed to new format

[deepakdinesh1123]

While writing new request response benchmarks I noticed that the URLs in benchmarks directories that had been added to the main urls.py file sometimes overlapped each other and while writing adding newer URLs one had to take into account the existing URLs and make sure that the new URL did not overlap with some other URL, so I have tried to add a new format for adding URLs here

• in the benchmark directory add the URLs to the urls.py file
• in the main urls.py file add the URL as

  urlpatterns.append("benchmark_name/", include('benchmarks.benchmark_type.benchmark_name.urls'))

  this way new URLs can be added without worrying about the existing ones

I will update the README if this gets approved
