Yes.

In the past we used a model where you needed 1 class per region. This approach isn't as scalable and nice to we deprecated it in favor of using a single constant and class which constructor takes `region` argument.

With this new approach you specify a region when instantiating a class so multiple classes and constants are not desired and needed anymore. For example:

```python
cls = get_driver(Provider.OUTSCALE_SAS)
driver = cls('api key', 'api secret', region='us-east-1')
```
