Analytics metadata are not represented by objects.

If you do a query, and ask for metrics, you can do something like this:

result = cluster.query("SELECT * FROM `beer-sample` where type = 'brewery' and name = 'Kona Brewing'", QueryOptions(metrics=True))

t = result.metadata().metrics().execution_time()

and t is a timedelta.

However, analytics queries don't represent the metadata as an object, so there is no corresponding metrics() call. Nor is there a corresponding metrics object to use, etc...

This is the issue in CBSC-8974.

At one time I think this returned the QueryMetaData and QueryMetrics which is ok. But maybe something changed? This is not RFC-compliant, and doesn't match the docs. Of course, the docs are wrong too - note CamelCase. There is a separate ticket coming for that.
