utils: add uefi.py
Add UEFI related utilities inside a new utility module: uefi.py _check_efibootmgr_json ====================== Check if the system efibootmgr executable supports JSON output. This is a private function used only by other functions from uefi.py. is_uefi_supported ================= Check if the system supports UEFI firmware. run_efibootmgr_json =================== Runs efibootmgr with json output support. Return the JSON output as a Python dict. efibootmgr_create_bootentry =========================== Create nvram boot entry. This bootentry is usually later set to boot next just once via "BootNext" nvram variable. efibootmgr_delete_bootentry =========================== Delete a nvram boot entry. Used to avoid duplicates when booting the same disk and partition from a given client. efibootmgr_bootnext =================== Set nvram "BootNext" variable to a given boot entry so after client reboot, PXE is not executed and the given boot entry takes precedence. Add dependency with efibootmgr version >= 18, and efibootmgr JSON output which is currently out of tree from util-linux repo.
