[SPARK-14133][SQL] Throws exception for unsupported create/drop/alter index , and lock/unlock operations.

## What changes were proposed in this pull request?

This  PR  throws Unsupported Operation exception for create index, drop index, alter index , lock table , lock database, unlock table, and unlock database operations that are not supported in Spark SQL. Currently these operations are executed executed by Hive.

Error:
spark-sql> drop index my_index on my_table;
Error in query:
Unsupported operation: drop index(line 1, pos 0)

## How was this patch tested?
Added test cases to HiveQuerySuite
