Add support for controlling the generated table name in the object storage

[sheinbergon]

Describe the enhancement requested

As of today, generated iceberg table names strictly adhare to the model file name.
While the view path is configurable from the scema, and the view name from the alias, the source table name cannot be modified.

Justification for this enhancement

This would allow for cleaner datalake layout, especially when using glue as the object storage source, where nested directories are not supported

Hey @sheinbergon, you mean using the alias for the table name before resorting to the file name? Or an actual name config option? Which one do you believe to be more appropriate?
