[BUG] Error in the Agent role, Firewall seems to be only installed if checkmk_agent_server is an ip address about ansible-collection-checkmk.general HOT 3 OPEN

I have not tested this yet, but from a quick look at the code this issue seems valid.

Now there are different approaches in how to handle this. In general, we need to check first, whether the variable checkmk_agent_server is an IP. Based on that we can use the IP, or we need to look up the IP address. While this sounds trivial, there can be several caveats: Firstly, is the name resolvable? If so, is the resolved IP the correct one (thinking about NAT here). And there is probably more.

Of course one could go the less smart way and just add the internally-used variable checkmk_agent_server_ip to the defaults and set it explicitly. That would make things easier on the one hand, but more error-prone on the other.

I need to think about this and look at the available options from a technical perspective.
