IMPALA-11573: Certain methods used by the replanning feature can be improved
This patch improves certain methods used by the replan feature
(IMPALA-10992) so that they can be called by the external frontend
component in Hive. Specifically, the declaration of these methods
becomes public static, and the initialization of a static data
member checks whether the dependent object exists.
Testing:
1. Run unit tests;
2. Run "core" tests.

> For ability to run large queries on larger executor group mapping to
