Refs #27847 - Set parameter mapping

[ekohl]

In puppet-certs master the default values are loaded via params.pp to workaround kafo limitations. This configures kafo to actually find it. Otherwise it can't load the defaults and the values are nil.

It can't generate the defaults but not sure why.

$ bundle exec $INSTDIR/sbin/foreman-proxy-certs-generate --help

Could not get default values, check log file at /tmp/tmp.oueXiC0vj1/var/log/foreman-installer/foreman-proxy-certs-generate.log for more information

The command "bundle exec $INSTDIR/sbin/foreman-proxy-certs-generate --help" exited with 25.

Error: Evaluation Error: Operator '[]' is not applicable to an Undef Value. (file: /tmp/tmp.sAudVOhpMm/share/foreman-installer/modules/certs/manifests/foreman_proxy_content/params.pp, line: 9, column: 18)

The problem is $facts['networking']['fqdn'] which is the modern fact, but that requires facter 3. In bundler we can only have facter 2 which means $facts['networking'] is undef. undef['fqdn'] doesn't work.

💚 due to theforeman/puppet-certs#260 being merged.
