Float to int cast behaviour

[oleggator]

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      |
+--------+

I think we would need to support configuration in arrow-rs first. The actual casting is here https://github.com/apache/arrow-rs/blob/e28cf44e65cdd1fefaa1b857ca4336e7a9da5d06/arrow-cast/src/cast/mod.rs#L2177
