Add shortcut to iPXE URL
In some cases the iPXE url could be passed through as a parameter to infrastructures which support iPXE as a boot method, eg. Vultr.
Currently to obtain the iPXE url, it's required to first input a fake MAC address and then preview the generated iPXE template to obtain the token. It may be useful if a provisioning method for iPXE could involve no requirements of a MAC address and a shortcut to the iPXE url with token provided to the user.
By iPXE url I'm referring to http://foreman/unattended/iPXE?token=xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx
