Description

RHEL 7.5+ added Kernel Address Randomization which improves security but also is causing issues when kexecing systems. Let's add this option to kexec when booting Anaconda and also into discovery image (global default templates) to prevent kexec issues. This will not carry over to Grub2 into the installed system.

I have at least two reports from downstream that this helped.

Upstream also confirms this option helped in one case: https://community.theforeman.org/t/pxe-less-discovery-host-reboots-when-provisioning/13117/2
