iceberg - queryViaDuckDB - support sql catalog type

[sysadminmike]

Feature Description

Duckdb can query an iceberg table without needing to access the catalog to get the current metadata location. If a version-hint.text file exits it is possible to query like:

SELECT count(*) FROM iceberg_scan('s3://bucket/warehouse/namespace/tablename');

Perhaps providing the path for the iceberg_scan function from an argument for the cli would work?

Then a specific snapshot could be used as well.
