Foreman prefers PXEGrub2 UEFI loader for generic host
When new bare-metal host is created and all PXE template kinds are associated and set for selected OS, Foreman sets PXE loader in this order:
- PXEGrub2 UEFI
- PXELinux BIOS
- PXEGrub UEFI
We should still prefer BIOS as the primary options because this can end up with hosts not booting for users with BIOS-PXE workflow which is still the most used one.
