feat: check if all hosts are accessible

Check if executing tasks as root is permitted.

I understand what you mean while using Ansible in a production environment. We also utilize Ansible for development servers and workstations, and Wireguard facilitates access to a backend network for a range of automated administrative tasks.

To ensure seamless operation, we preliminary check to verify that all anticipated hosts are reachable. That simple measure serves two purposes:

1. It allows us to identify and address any connectivity issues early on, preventing potential delays or disruptions.
2. It prevents inadvertent creation of configurations that include missing hosts, which could lead to surprises and complications down the road.

Thx for ansible.builtin.include_role. I'll have a look at it too.
