##### SUMMARY
Use bigger roles namespace, by using the first 2 chars of each word:
`load_balancer_network` => `lobane`
For example, we have such cases:
- `rdns` => `r` => `rd`
- `route` => `r` => `ro`
##### 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.
