### What changes were proposed in this pull request?
Adds an opt-in itests/tez-yarn-it module with a Docker/Testcontainers-based
HDFS+YARN cluster and an end-to-end test that verifies hive-exec.jar is
localized when Tez runs on YARN.
### Why are the changes needed?
MiniTezCluster / TestMiniTezCliDriver do not exercise real YARN resource
localization, so regressions like skipping hive-exec.jar from
commonLocalResources are not caught today.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Ran locally with mvn test -Pitests,tez-yarn -pl itests/tez-yarn-it
-Dtest=TestTezYarnLocalization#testQuerySucceedsWithAppJar, and also validated
on GitHub Actions (ubuntu-latest, native Linux amd64) using the same Maven
command after mvn clean install -DskipTests -Pitests -pl itests/tez-yarn-it
-am; the full end-to-end test is reliable on native Linux, while on Apple
Silicon Macs Docker runs amd64 images under QEMU and may time out during large
jar localization even though the test logic is correct.
