This template is used to pass command line options to kexec when reloading
kernel on a discovered host instead of rebooting. This is useful in PXE-less
environments. The template must generate JSON format with the following items
"kernel", "initram", "append" and "extra". The kexec command is composed in
the following way:
kexec --force --debug --append=$append --initrd=$initram $extra $kernel
Please read kexec(8) man page for more information about semantics.
Extra options like --reset-vga can be set via "extra" array.
