Moves image_info from cloud to proxy object

This makes image_info compatible with new sdk version
- This patch changes get_image (which is a cloud object method) to image.get_image (proxy object method)
- image.images accepts **query which is a dict object. So this patch changes the args passed to a dict. If properties is not specified it passes an empty dict.
- updates the documentation to reflect the actual returned parameters
- adds a ci test to list all images without specifying image name or property and assert no field is missing
- changes openstack_image to image in ansible return value
