Adds support for Redfish with:
* ``redfish`` hardware type
* ``redfish`` power interface that provides hard power
[on, off, reboot] and soft power [off, reboot]
* ``redfish`` management interface to set the boot device (PXE, disk,
cd-rom and bios) and its frequency (persistent or not); and NMI
injection SSL authentication
