rgw: use trace logs for RGW admin HTTP info

Debug logs for the RGW Admin Ops debugHTTPClient can leak credentials
used to access the Admin Ops API as well as credentials that may be
returned for any buckets/users. Use trace logs instead, which users are
unlikely to enable in production to mitigate the risk.
