Yuming Wang 7f53116f77 [SPARK-24570][SQL] Implement Spark own GetTablesOperation to fix SQL client tools cannot show tables 
## What changes were proposed in this pull request?

For SQL client tools([DBeaver](https://dbeaver.io/))'s Navigator use [`GetTablesOperation`](a744457076/sql/hive-thriftserver/src/main/java/org/apache/hive/service/cli/operation/GetTablesOperation.java) to obtain table names.

We should use [`metadataHive`](95d172da2b/sql/hive-thriftserver/src/main/scala/org/apache/spark/sql/hive/thriftserver/SparkSQLEnv.scala (L52-L53)), but it use [`executionHive`](24f5bbd770/sql/hive-thriftserver/src/main/scala/org/apache/spark/sql/hive/thriftserver/HiveThriftServer2.scala (L93-L95)).

This PR implement Spark own `GetTablesOperation` to use `metadataHive`.

## How was this patch tested?
