CI Test will sometimes run for 6 hours (before getting auto-terminated by GitHub):
- apache#14808
- apache#14680
This is a problem because:
- It will increase our usage of GitHub Runners. Which may overrun the [GitHub Actions Budget](https://infra.apache.org/github-actions-policy.html) allocated by ASF.
- Suppose right after CI Test there's another build. If CI Test runs for all 6 hours, then the build after CI Test will never run.
For this PR: We assume that Every CI Job (e.g. risc-v-05) will complete normally within 2 hours. If any CI Job exceeds 2 hours: This PR will kill the CI Test Process `pytest` and allow the next build to run.
