[EPIC] Data driven integration test framework.

### What's the feature are you trying to implement?

Use datafusion and sqllogictest to build a data driven integration test framework.

See #581 for an overview.

### Willingness to contribute

I would be willing to contribute to this feature with guidance from the Iceberg Rust community

Start by reading the overview in issue #581 and review how DataFusion and sqllogictest are intended to support this work. Define the integration test framework's scope and completion criteria with the Iceberg Rust community before implementation.
