1. Proposed title of this feature request

 Clean up and add own entry of UEFI install while doing PXE based install. This shall help the PXE installs to boot using the disk once the coreos-installer writes to the disk.
Currently, it needs a manual switch to force boot from disk where no UEFI entry is created.

Ref : OCPBUGS-29693

I have tested on VM's as well and the solution is to either add a custom service or manually create a EFI entry to force the boot using disk. Though on VM's it boots due to stale entries inherit same location for shim things, on fresh hardware it won't or hardware like FC630 it fails.
