Review comment:
Thanks for taking a look at this. The reason I am doing this is because
I saw other `DataFrameReader/Writer` APIs have added the support for DataSource
V2 multiple catalogs, for example, `DataFrameWriter.insertInto` and
`DataFrameWriter.saveAsTable`, so I thought all the `DataFrameReader/Writer`
APIs need to support DataSource V2 multiple catalogs as well.
