Review Comment:
This won't do what you expect. Go embedding doesn't work like C++
polymorphism, this method isn't a virtual call and will *always* call the
BaseServer version of `CancelFlightInfo`. A user would need to override
`CancelQuery` in order to call their own `CancelFlightInfo`. So it's probably
not worthwhile to have this base implementation.
You should move this implementation to `flightSqlServer` and then call
`f.srv.CancelFlightInfo` like we do for the other actions.
