For some tests, we need to specify image cluster size for
a given image. Make it possible to specify it so qemu-img
is called with the right parameters. This way we can state
things like:
images += ' stg1 stg2'
image_name_stg1 = storage_4k
image_cluster_size_stg1 = 4096
image_format_stg1 = qcow2
image_name_stg2 = storage_64k
image_cluster_size_stg2 = 65536
image_format_stg2 = qcow2
in the configuration file for a test
