Ramdisk: do not require image_source

Browse Source 
Because of the way validation works, the ramdisk deploy interface
currently requires an image_source in addition to kernel/ramdisk.
After 1d6441cc34 it is no longer
necessary, and this change removes this requirement.

.. note::
The requirement to pass ``image_source`` is artificial and will be fixed
in a future version of the Bare Metal service.
Before the Xena release, the ``image_source`` field was also required::

The ``ramdisk`` deploy interface no longer requires a fake ``image_source``
value to be provided when ``boot_iso`` is not used.
