Add support for extra properties in an image

This patch adds a new setting for images, extra_properties.
This field is a dict and can be used to create a 3-part image
by setting the kernel_id and the ramdisk_id of the main image.

Unit tests have been added to set some generic property, for
creation of the 3-part image, and for creating an instance
with that 3-part image
