Bug 1686654

In Fedora-Rawhide-20190306.n.1, all firewall tests failed. There seem to be two separate bugs in two different tests. In this one, an install is run from the server DVD with a kickstart - http://fedorapeople.org/groups/qa/kickstarts/firewall-configured-net.ks - that says 'firewall --port=imap:tcp,1234:udp,47 --service=ftp' (and installs only '@core' packages). The install completes successfully, and the test then boots the installed system and runs 'firewall-cmd --state', expecting it to succeed (success indicates the firewall is running, failure indicates it is not). It fails, with the output 'not running'. Looking at the firewalld service logs, we see this:

Mar 06 17:22:51 localhost.localdomain systemd[1]: Starting firewalld - dynamic firewall daemon...
Mar 06 17:22:52 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon.
Mar 06 17:22:52 localhost.localdomain firewalld[578]: WARNING: modinfo command is missing, not able to detect conntrack helpers.
Mar 06 17:22:53 localhost.localdomain firewalld[578]: ERROR: Failed to load nf_conntrack module:
Mar 06 17:22:53 localhost.localdomain firewalld[578]: ERROR: Raising SystemExit in run_server
Mar 06 17:22:53 localhost.localdomain systemd[1]: firewalld.service: Succeeded.

I'm not sure if the lack of modinfo is the *cause* of the subsequent failure, I will do a manual test install and check it out.

Proposing as an F31 Beta blocker per "..Supported install-time firewall configuration options must work correctly." - https://fedoraproject.org/wiki/Basic_Release_Criteria#Firewall_configuration , this test is specifically meant to enforce that criterion. Will move to F30 if this also affects it, once we finally get a compose.
