        Build a SparkCatalog to be used for Iceberg operations.

        The default implementation creates a new SparkCatalog with the session catalog's name and options.

        Parameters:
        name - catalog name
        options - catalog options
        Returns:
        a SparkCatalog to be used for Iceberg tables
