add FreeIPA test disks (with kickstarts) and update InstallGuide

Summary:
This goes along with the openqa_fedora commit to add the tests.
I didn't update the Docker instructions yet because I don't
quite remember how that goes. It might need a whole different
setup using some other networking...thing...

Test Plan: See https://phab.qadevel.cloud.fedoraproject.org/D831
