IMPALA-8369 (part 3): Hive 3: fix test_permanent_udfs.py for Hive 3 support
This fixes two issues in test_permanent_udfs.py:
- two of Hive's built-ins were ported to the new GenericUDF interface
which Impala can't execute. These UDFs are now excluded from the test
when running with Hive 3.
- The 'hive' commandline is deprecated nowadays, so the test now uses
the standard HS2 approach to run Hive queries. Hive 2+ caches UDFs, so
now that we are connecting to an already-running HS2 rather than
starting a new standalone 'hive' command, we need to explicitly
invalidate that cache by using 'RELOAD FUNCTION' after making changes
to UDFs in Impala.

> Project: IMPALA
> Issue Type: Improvement
> Reporter: Vihang Karajgaonkar
> Assignee: Vihang Karajgaonkar
> Priority: Major
> Labels: impala-acid
>
> Currently, Impala only works with Hive 2.1.1. Since Hive 3.1.0 has been
> released for a while it would be good to add support for Hive 3.1.0 (HMS
> 3.1.0). This patch will focus on ability to connect to HMS 3.1.0 and run
> existing tests. It will not focus on adding support for newer features like
> ACID in Hive 3.1.0 which can be taken up as separate JIRA.
> It would be good to make changes to Impala source code such that it can work
> with both Hive 2.1.0 and Hive 3.1.0 without the need to create a separate
> branch. However, this should be a aspirational goal. If we hit a blocker we
> should investigate alternative approaches.
