@grub_pass seems deprecated in the default kickstart template
Description of problem:
We have this in the default kickstart template:
bootloader --location=mbr --append="<%= host_param('bootloader-append') || 'nofb quiet splash=quiet' %>" <%= @grub_pass %>
According to https://community.theforeman.org/t/grub-pass-ks-console/10610, @grub_pass is defined nowhere and the code is dead. Thus, we should change the template to use @host.grub_pass so that people can define grub_grass as a host/hg/global param.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. nowhere to define @grub_pass. The only way to change the booloader password is to clone the template. However, in same cases, people do not want to clone.
Can not define @grub_pass to pass the bootloader password
Can define @grub_pass to pass the password.
Fixes #32394 - Use grub_pass macro instead of variable
The default Kickstart template uses obsolete @grub_pass variable
which are not being set anywhere. Maybe it's due to typo or else.
I suggest to use macro instead so it's possible to set the password
via host params and do not clone the template for this purpose only.
