[SPARK-19921] [SQL] [TEST] Enable end-to-end testing using different Hive
metastore versions.
### What changes were proposed in this pull request?
To improve the quality of our Spark SQL in different Hive metastore
versions, this PR is to enable end-to-end testing using different versions.
This PR allows the test cases in sql/hive to pass the existing Hive client to
create a SparkSession.
- Since Derby does not allow concurrent connections, the pre-built Hive
clients use different database from the TestHive's built-in 1.2.1 client.
- Since our test cases in sql/hive only can create a single Spark context
in the same JVM, the newly created SparkSession share the same spark context
with the existing TestHive's corresponding SparkSession.
### How was this patch tested?
Fixed the existing test cases.
