[ci-v2-notice] Notice: We are gradually rolling out the new ci-v2 system.

Legacy CI jobs remain unaffected, you can just ignore ci-v2 if you don't want to run it.
Additional "ci-v2/*" checkers will run for this PR to ensure the new ci-v2 system is working as expected.
For tests that exist in both v1 and v2, passing in either system is considered PASS.

To rerun ci-v2 checks, comment with:

/ci-rerun-code-check // for ci-v2/code-check
/ci-rerun-build // for ci-v2/build
/ci-rerun-ut-integration // for ci-v2/ut-integration
/ci-rerun-ut-go // for ci-v2/ut-go
/ci-rerun-ut-cpp // for ci-v2/ut-cpp
/ci-rerun-ut // for all ci-v2/ut-integration, ci-v2/ut-go, ci-v2/ut-cpp
/ci-rerun-e2e-arm // for ci-v2/e2e-arm
