Previously, we moved cql3::functions::function to the db::functions namespace, since functions are a part of the data dictionary, which is independent of cql3. We do the same now for scalar_function, since we wish to make use of it in a new db::functions::stateless_aggregate_function. A stub remains in cql3/functions to avoid churn.
