[SPARK-21617][SQL] Store correct metadata in Hive for altered DS table.
This change fixes two issues:
- when loading table metadata from Hive, restore the "provider" field of
CatalogTable so DS tables can be identified.
- when altering a DS table in the Hive metastore, make sure to not alter
the table's schema, since the DS table's schema is stored as a table
property in those cases.
Also added a new unit test for this issue which fails without this change.
