CentOS Stream 9 update broke Packstack/OpenStack install

[W. Michael Petullo]

I installed OpenStack using Packstack on CentOS 9. After some time of service, I ran "dnf update" to update the underlying operating system. After doing this, httpd failed to start. After some investigation, it appeared that the new httpd packages perturbed the Packstack httpd configuration. This led to three things being configured twice:

1. An Alias for /icons/.
2. The Listen 443 statement.
3. The loading of MPM modules.

Any one of these prevents httpd from starting.

Here is a patch that represents what I had to fix to get httpd to run again:
