Currently after successful bootstrap, node' PXE config is generated from localboot template, but using grub and PXEGrub templates this fails, because node config is always generated from same template 'PXE Localboot config', which is PXELinux specific configuration and is not suited for grub.

I made small changes in Foreman' codebase to conditionally generate node' PXE config from different localboot templates (will submit PR soon).
