Provisioning fails when firewalld and python3-firewalld aren't installed on the infra box

[rhawalsh]

Running a Fedora 36 infrastructure system (using Vagrant's public repository fedora/36-cloud-base image) with a freshly checked out version of Bunsen ends up with failed provisioning.

Python Module not found: firewalld and its python module are required for this module,                         version 0.2.11 or newer required (0.3.9 or newer for offline operations)

If I then install python3-firewall on the infrastructure box, it gets further but still ends up failing.

ERROR: Failed to load full stock configuration. This likely indicates a system level issue, e.g. the firewall backend (nftables, iptables) is broken. All hope is lost. Exiting.     

If I then install firewalld, provisioning is able to continue as expected.

I am going to try to reproduce with Fedora 37 and Fedora 38 (if that image is available; I'm not sure atm).

This also seems to apply to the farm role as well, but not resources.
