I searched for its usage to see if it needed refactoring, but it isn't referenced anywhere in the project as far as I can tell.

```
~/Development/monster $ grep 'template_file' -R .
Binary file ./monster/config.pyc matches
./monster/deployments/chef_deployment.py:        template_file = ""
./monster/deployments/chef_deployment.py:            template_file = "default"
./monster/deployments/chef_deployment.py:            template_file = branch.lstrip('v')
./monster/deployments/chef_deployment.py:            if "rc" in template_file:
./monster/deployments/chef_deployment.py:                template_file = template_file.rstrip("rc")
./monster/deployments/chef_deployment.py:            template_file = template_file.replace('.', '_')
./monster/deployments/chef_deployment.py:                                    template_file))
```

The only time `template_file` is referenced is as a variable storing a string, not calling the aforementioned function.
