ModuleNotFoundError: No module named 'CloudFlare' after running make up-reqs

As described in your doc i ran:
```
$ make up-reqs
```

This updates all python dependencies, but it looks like the cloudflare package changed its module name (capitalisation).

One of two things probably should happen:
* pin an older lib version in the `requirements.in` file
* update the requirements and change the module name usage.
