Steve Baker 71ccbf5955 Raw image size estimation improved
Adds the `[DEFAULT]raw_image_growth_factor` configuration option which
is a scale factor used for estimating the size of a raw image converted
from compact image formats such as QCOW2. By default this is set to 2.0.

When clearing the cache to make space for a converted raw image, the full
virtual size is attempted first, and if not enough space is available a
second attempt is made with the (smaller) estimated size.
