feat: remove hcloud_ prefix from all modules names (#390)

##### 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.
