[TRAFODION-3009] Streamline error handling in Executor utility commands
Changes to avoid allocation of ComDiagsArea in some more places unless it is
needed to pass errors or warnings.
[TRAFODION-2917] Refactor Trafodion implementation of hdfs scan for text
formatted hive tables
Disabling USE_LIBHDFS_SCAN by default. The new implementation of Hdfs Scan
is now used to
scan the text type hive files.
Hdfs Scan is now stopped gracefully when the hive scan is cancelled. This
avoids the random
core seen with new implementation.

> Reporter: Selvaganesan Govindarajan
> Assignee: Selvaganesan Govindarajan
> Priority: Major
>
> Executor utility commands are the commands that issue sql statements during
> its execution to complete its task. These operators are derived from
> ExExeUtilTcb operator in Trafodion. These commands assume ComDiagsArea is
> allocated in advance. This is not in accordance with the design as outlined in
