[SPARK-24252][SQL] Add DataSourceV2 mix-in for catalog support. ## What changes were proposed in this pull request? This adds a mix-in to `DataSourceV2` that allows implementations to support catalog operations: load table (for schema), create table, drop table, and alter table. This does not include the proposed transactional API. ## How was this patch tested? Work in progress. This is for discussion right now.
