No 'firewalld' on Rocky9

[dominikl]

It looks like firewalld is not installed on Rocky9, so this section causes an issue:
https://github.com/ome/ansible-role-iptables-raw/blob/master/tasks/main.yml#L15

TASK [ome.iptables_raw : iptables-raw | disable firewalld] **********************************************************************************************************************
fatal: [2f5d1f82-2aad-433b-ab9f-98c5fe25ffa5]: FAILED! => {"changed": false, "msg": "Could not find the requested service firewalld: host"}

Is it possible to have some kind of soft fail here if the service is not installed, instead of a fatal error?

Adding

- name: iptables-raw | print service facts
  become: true
  debug:
    var: ansible_facts.services

to the role yields

        "firewalld.service": {
            "name": "firewalld.service",
            "source": "systemd",
            "state": "stopped",
            "status": "not-found"
        },    

so the assumption that you can rely on the list of returned services is not sufficient and more is needed.
An alternative workflow (suggested here) would be to ignore the failure is "Could not find the requested service" is returned in the message.

For IDR, a workaround might be to set iptables_raw_disable_firewalld: False as firewalld is not installed by default.
