```
public class SystemKeyspaceMigrator41
extends java.lang.Object
```
Migrate 3.0 versions of some tables to 4.1. In this case it's just extra columns and some keys that are changed.
Can't just add the additional columns because they are primary key columns and C* doesn't support changing key columns even if it's just clustering columns.
