Float to int cast behaviour

At the moment, DataFusion casts floats to integers using the floor function.
Is it possible to configure this behavior?

## Actual
```
select cast(2.8 as int) as result;
+--------+
| result |
+--------+
| 2 |
+--------+
```

## Expected
This way work Postgresql and MySQL.
```
select cast(2.8 as int) as result;
+--------+
| result |
+--------+
| 3 |
+--------+
```

The issue provides SQL examples but names no files or tests. Start by tracing DataFusion's float-to-integer CAST handling and clarify whether rounding should be configurable or changed by default. Done when the chosen behavior is specified and covered by tests for 2.8, including the supported configuration if one is added.
