Review comment:
If it is a create view statement, we fail with `Create view is not supported
in cbo return path.`. I would expect that since view creation is not supported
in cbo return path, we just either 1) do not use return path for view creation,
or 2) we only fail if we are setting this to `true`?

> Instead of having a boolean for hive.cbo.returnpath.hiveop it should be
> on/off/supported. In case of "supported" it should be used for a subset of
> commands which are already verified to be able to work with return path. This
> is a temporary solution for the time while we are developing return path,
> before making it the only way to handle commands.
