Foreman » Smart Proxy

Foreman Proxy must be enhanced with new PXE variant "Pxegrub2" to allow deploying configuration files in "grub2/" folder. In addition to that, Pxegrub (version 1) must deploy two configuration files instead of one now to support both BIOS and UEFI naming conventions (grub/menu.lst vs grub/efidefault and grub/menu.lst.01aabbccddeeff vs grub/01-AA-BB-CC-DD-EE-FF). Also, Pxegrub variant will use new base directory "grub/" instead of "boot/grub/" for consistency with "grub2" and "pxelinux.cfg/".
