entry point to dump all config values

will use this for debugging whether puppet is inserting all the values in the right places after my upcoming changes

this can be run with 
```sep print_config```
You should really leave comments such as this as docstrings, since then they're visible in the interpreter, e.g. if someone says

```python
>>> help(print_config)
```

Not a huge deal, definitely something to keep in mind for future reference.
