whereClause should support jdbc dialect

> --------------------------------------------------------------------
>
> Key: SPARK-28587
> URL: https://issues.apache.org/jira/browse/SPARK-28587
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.3
> Reporter: wyp
> Priority: Minor
>
> When we use JDBC data source to search data from Phoenix, and use timestamp data type column for partitionColumn, e.g.
> {code:java}
> val url = "jdbc:phoenix:thin:url=localhost:8765;serialization=PROTOBUF"
> val driver = "org.apache.phoenix.queryserver.client.Driver"
> val df = spark.read.format("jdbc")
> .option("url", url)
> .option("driver", driver)
> .option("fetchsize", "1000")
> .option("numPartitions", "6")
> .option("partitionColumn", "times")
> .option("lowerBound", "2019-07-31 00:00:00")
> .option("upperBound", "2019-08-01 00:00:00")
> .option("dbtable", "test")
> .load().select("id")
> println(df.count())
> {code}
> there will throw AvaticaSqlException in phoenix:
> {code:java}
> org.apache.calcite.avatica.AvaticaSqlException: Error -1 (00000) : while preparing SQL: SELECT 1 FROM search_info_test WHERE "TIMES" < '2019-07-31 04:00:00' or "TIMES" is null

> the reason is because JDBC data source's partition whereClause doesn't support jdbc dialect. We should use jdbc dialect to compile '2019-07-31 04:00:00' to to_timestamp('2019-07-31 04:00:00')
