Queue a server-side trace of a saved ad destination

Queues a trace of one destination URL that a saved ad of the project pointed to (use the url from list_keyword_ads or the observations list; other URLs are refused). Use it to inspect the recorded destination path and any affiliate IDs in that path. Our servers follow it hop by hop with a clear user agent and no cookies, recording each status code, the redirect mechanism, the final URL and any affiliate IDs present. It runs from our servers, not the searcher's country or device, so a location- or device-dependent redirect may differ. Script redirects are read from page source without running it. Each new trace uses one of the account's daily traces (resets 00:00 UTC); repeating the call for the same URL within the same UTC hour returns the same trace and uses nothing. The trace usually finishes within a minute: read it with get_redirect_chain. Requires the write scope and explicit user authorization.
