In v2, we use the link header during paginations to know when there are
more images available in the server that could be returned in the same
request. This way, it's possible to iterate over the generator returned
by list and consume the images in the server.
However, it's currently not possible to tell glanceclient the exact
number of images we want, which basically means that it'll *always* go
through the whole list of images in the server unless the limit is
implemented by the consumer.
