Change subject: IMPALA-10197: Add KUDU_REPLICA_SELECTION query option ...................................................................... IMPALA-10197: Add KUDU_REPLICA_SELECTION query option Sometimes it is useful to target queries at the leader only replica instead of the default closest replica. This patch added new query option KUDU_REPLICA_SELECTION with which to choose replicas for Kudu amongst multiple Kudu replicas. Removed variable FLAGS_pick_only_leaders_for_tests since its usage can be replaced by the new query option. Added new planner and end-to-end tests for the new query option. Testings: - Passed exhaustive tests.
