##### SUMMARY This simplifies the name of the modules from `hetzner.hcloud.hcloud_firewall` to `hetzner.hcloud.firewall`. While maintaining backward compatibility with the old names. Further changes such as updating the test or the documentation will be done in a future PR to maintain the git history when squashing the PRs. ##### ISSUE TYPE - Feature Pull Request
