Description of problem:
For reasons unknown to me, a user had a broken puppet-lvm module in /etc/puppetlabs/code/modules/puppetlabs-lvm/, which resulted in the following error when Puppet tried to load it:
Error: Could not run: cannot load such file – puppet_x/lvm/output

Such a local issue should not have an effect on the execution of the Installer (as it should not load random modules from /etc/puppetlabs, those could be incompatible with the contents of the installer).

Kafo, when running Puppet, does generate a custom configuration to avoid this problem:

1. cat /tmp/kafo_installation20220818-28102-108x1gp/puppet.conf
   [main]
   basemodulepath = /usr/share/foreman-installer/modules:/usr/share/gems/gems/kafo-6.4.0/lib/kafo/../..//modules
   color = false
   environmentpath = /tmp/kafo_installation20220818-28102-108x1gp/environments
   evaltrace = true
   factpath = /tmp/kafo_installation20220818-28102-108x1gp/facts
   hiera_config = /usr/share/foreman-installer/config/foreman-hiera.yaml
   noop = false
   profile = false
   reports =
   show_diff = true

However, we also have a `apply_puppet_code` function in our hooks (https://github.com/theforeman/foreman-installer/blob/43067e91db3439d662adad313ac43853b4cf0992/hooks/boot/01-kafo-hook-extensions.rb#L34-L37) which does NOT pass a custom config and thus loads the global one from /etc, which DOES read the modules and explodes.

This results in the following error when the installer is executed:
2022-08-18 10:17:51 [ERROR ] [root] Failed to ensure rh-postgresql12-postgresql-server, rh-redis5-redis, foreman-selinux, katello-selinux, candlepin-selinux, pulpcore-selinux are installed
