Inject console parameters in GRUB2

[mloviska]

Due to https://bugzilla.suse.com/show_bug.cgi?id=1229336 the console= parameters are gone, jeos-firstboot wizard shows in ttyS0 instead of tty.
We need to inject these parameters at boottime and bring back the grub2 handler module. -> https://src.suse.de/products/SL-Micro/pulls/59/files

If the graphical console is no longer used by the kernel at all that's a severe product bug and IMO a ship stopper.

Seems legit, although I do not like all that blind up-down fixed movements... Wouldn't it be adequate to check if the selected option is the correct before accepting?

The emacs like shortcuts are insufficient for our needs, so the navigation options in the submenu is very limited. At most we can add more needles
