Review comment:
I don't think that we want to use `CatalogLoader`. The use case for that
is a bit different: it is for Hive, where `Configuration` is the _correct_ way
to pass options. That loader should call whatever dynamic loader function we
introduce in this PR. I also think that it shouldn't be located in the
iceberg-hive-metastore module. That should be in iceberg-mr.
