Automatic merge from submit-queue Node Conformance Test: Add system verification For #30122 and #29081. This PR introduces system verification test in node e2e and conformance test. It will run before the real test. Once the system verification fails, the test will just fail. The output of the system verification is like this: ``` I0909 23:33:20.622122 2717 validators.go:45] Validating os... OS: Linux I0909 23:33:20.623274 2717 validators.go:45] Validating kernel...

The validating framework is ready. The specific validation items could be added over time. @dchen1107 /cc @kubernetes/sig-node |
