[AIRFLOW-284] HiveServer2Hook fix for cursor scope for get_results

Dear Airflow Maintainers,

Please accept this PR that addresses the following issues:
- *(replace with a link to AIRFLOW-X)*

Detail:
The function `get_results` implemented in the `HiveServer2Hook` does not execute multiple commands passed to it in a list, in the singular cursor scope. This has caused SQL statements that depend on the execution of `add jar` and `set` commands to fail as they are being executed in different cursor scopes which are not persistent.
The code has been updated to have the cursor object persistent.

Testing Done:
