IMPALA-8369: Fix HMS integration tests for Hive 3

Hive 3 changed the output format of the 'describe formatted
<table> <column>' command. Added a new function that can parse
the new output.

Hive 3 also got more permissive during scanning, e.g. it can scan
a Parquet column of INT type while the HMS metadata for that column
is STRING. It does automatic conversion during scanning. However,
it doesn't do the opposite, i.e. when the Parquet column type is
STRING and the HMS column type is INT it raises an exception. Extended
the test with this case.

> 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.
