API-90 - use rel links for streaming results

Rather than iterating over numeric counts

https://clever.atlassian.net/browse/API-90
We do get the uri from the next link (`next_link.uri`) but I'm not sure without parsing them at all since @query._options needs to get filled in. Though I think replacing the entire query option would be better since there are cases like created_since where we actually omit existing parameters to make paging work.
