CI run looks good with some known flaky tests. None of them are related with
the patch.

> Add a virtual table for exposing prepared statements metrics
> ------------------------------------------------------------

> Key: CASSANDRA-17224
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17224
> Project: Cassandra
> Issue Type: Improvement
> Components: Feature/Virtual Tables, Observability/Metrics
> Reporter: Benjamin Lerer
> Assignee: Shailaja Koppu
> Priority: Normal
> Labels: AdventCalendar2021, lhf
> Fix For: 4.x

> Time Spent: 10.5h
> Remaining Estimate: 0h
>
> There are some existing metrics within {{CQLMetrics}} that provide metrics
> about prepared statements. We should expose those through a virtual table.
> +Additional information for newcomers:+
> A new class should be created for representing the new Virtual Table in
> {{org.apache.cassandra.db.virtual}}. You can look at {{ThreadPoolsTable}} for
> an example.
> The new table will need to be registered in {{SystemViewsKeyspace}}.
> Some unit tests will need to be added. For some example of virtual table
> tests you can look at {{SystemPropertiesTableTest}} and for some example of
> test around prepared statement metrics you can look into {{CQLMetricsTest}}.
