Add limit to rank in list of upload/index records

[efritz]

We have a performance issue on dotcom with the precise indexes endpoint. One of the dominating points of the query is the rank in queue, which we need to sort the entire set of queued uploads. This cost grows linearly with queue size, regardless of the filters.

Instead we should only count the first 1000 or so in the queue, and display a more generic "in queue" message when listing precise indexes. When fetching a single index we can still get the full rank.
