Deploy fai config (the one in nfs) to HOST or default faiserver

+note FAI_ACTION might be able to be set elsewhere, like in grub for this case

+-d DISTRO DISTRO for setting up fai class DESKTOP packages, for preinstalling stuff.
+-t TARGET_HOST Copy only secrets for TARGET_HOST into the config space. Useful for virtual server
+ on hardware we don't control.
+-h|--help Print help and exit
Note: uses paths specific to authors machine.
