Title: Add support for server availability zone

Since [ProfitBricks API 1.2](https://www.profitbricks.com/de/en/iaas-developer-center/profitbricks-api/) the servers support different availability zones.

Besides adding the `availability_zone` parameter to the `Server` class in 0a0cebf, this pull request also includes some cleanup work on the repository.
