[SPARK-21150][SQL] Persistent view stored in Hive metastore should be case
preserving
## What changes were proposed in this pull request?
This is a regression in Spark 2.2. In Spark 2.2, we introduced a new way to
resolve persisted view: https://issues.apache.org/jira/browse/SPARK-18209 , but
this makes the persisted view non case-preserving because we store the schema
in hive metastore directly. We should follow data source table and store schema
in table properties.
## How was this patch tested?
new regression test
