add a query parameter in get scan status API which control whether return detail scan task status info

Created by: deltay

When I want to return scan task status using /scans/XXXXXXXXX, it return very detail info which result in a large http response . It would be better if there is a query parameter which control whether return detail scan. Fox example, If GET /scans/XXXXXXXXX?detail=yes or GET /scans/XXXXXXXXX then return all message as before. If GET /scans/XXXXXXXXX?detail=no then do not return seen_errors,seen_sitemap and seen_issues
