Description
Datafusion supports url table used like this:
select * from 'S3://bucket1/dataset2'
We could support this by implement a lance UrlTableFactory. And beyond xxx.lance tables, we should also accept xxx.parquet, 'xxx.csv', 'xxx.json' as long as datafusion has supported them.

Research direction
Start by tracing DataFusion's URL-table handling and the proposed lance UrlTableFactory. Verify how a query such as SELECT * FROM 'S3://bucket1/dataset2' is resolved, then define completion as support for .lance, .parquet, .csv, and .json URLs wherever DataFusion supports those formats.
