Subject: [PATCH] Use datetime.now(utc) in MetricDatum

datetime.utcnow() is deprecated as of Python 3.12, and its use will
raise a DeprecationWarning. Since warnings are treated as errors, this
results in test failures under Python 3.12. Switch to using
datetime.now() with a timezone.utc parameter.
