### Summary Clickhouse SQL has an optional [`SETTINGS` clause](settings-clause) with `SELECT`s which can be used to configure [all kinds of options](settings). This PR adds a `settings` method to `ClickHouseQueryBuilder` to add these options to a `SELECT` query. All current (Clickhouse 24.4) settings keys are snake-case. Therefore I opted to use the settings keys directly as kwargs to the `settings` method, allowing passing multiple settings pairs in one call in a Pythonic/ideomatic way. [settings-clause]: https://clickhouse.com/docs/en/sql-reference/statements/select#settings-in-select-query [settings]: https://clickhouse.com/docs/en/operations/settings/settings ### Test Plan Added a unit test to exercise the new function.
