glanceclient image-list has no support for limit

[Flavio Percoco]

python-glanceclient's support for v2 has a built-in implementation for pagination. This is a nice and useful feature to have. Unfortunately, it does not have support for *limiting* the number of images that should be retrieved from the server. I believe that, in addition to page-size, there should be a limit CLI parameter (and keyword) supported in glanceclient.

    Add a `--limit` parameter to list operations

    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.
