[SPARK-12724] SQL generation support for persisted data source tables

This PR implements SQL generation support for persisted data source tables.  A new field `metastoreTableIdentifier: Option[TableIdentifier]` is added to `LogicalRelation`.  When a `LogicalRelation` representing a persisted data source relation is created, this field holds the database name and table name of the relation.
