All REST calls that go through the REST API interface log their results
to the JS console. Log entries include the HTTP status of the response,
the HTTP method used, the elapsed time in milliseconds and the original
URL of the request.
Note: because the URLs are not anonymized/sanitized these logs are not
sent to gr-reporting.
