Anita Kuno 8811ced007 Added limit to image-list in a preparatory step toward addressing bug 1001345.
Currently novaclient doesn't use the limit or marker params.
As a step to addressing bug 1001345 which requires pagination,
this patch introduces the use of limit as an option
passed to the image-list function.
