We have option 'max_limit' in quantum.conf. We can specific a special
value(example: -1) for
disable pagination. And if user didn't add 'limit' params in the url,
all items are returned in one
list operation. So pagination will be a optional feature. If user want
to use it, just add 'limit' params
in url.

When user didn't specific a limit value, we don't show the pagination links.

In next version, we can specific a default limit value. Then force limit
the maximum of items
are returned in one operation.
