Reduce logging levels for meter usage tests (#131935) (#131944)

This PR reduces the logging level of the test logging added in #111360 to Trace. The issue that logging was intended to investigate has been closed, and there doesn't appear to be any current need for this logging. If we need it in the future, it will be trivial to re-enable.
