Commit 3db89e6df08f2c859926bdf397e69099e21660d1 in impala's branch

IMPALA-12737: Add HS2 support to the InternalServer class.
The existing methods in the InternalServer class allow for retrieving
query results via tab delimited text. This method is not robust when
accuracy is needed for query results. This commit adds the ability to
use the HS2 protocol to execute queries with the results returned as
a vector of Thrift TRow objects. This new method is not used in this
commit but will be used in subsequent commits for IMPALA-12737.
Testing was accomplished by adding a new unit ctest.

> Priority: Critical
> Labels: workload-management
>
> In the Impala query log table where completed queries are stored, add lists
> of columns that were referenced in the query. The purpose behind this
> functionality is to know which columns are part of
> * Select clause
> * Where clause
> * Join clause
> * Aggegrate clause
> * Order by clause
> There should be a column for each type of clause, so that decisions can be
> made based on specific usage or on the union of those clauses.
> With this information, we will feed into compute stats command to collect
> stats only on the required columns that are using in joins / filters and
> aggegrates and not on all the table columns.
> The information can be collected as an array of
> [db1.table1.column1,db1.table1.column2]
