Add two separate probes, one for liveness and one for readiness. The liveness probe would check that the local individual node is up and running, or else restart the node, while the readiness probe would check that the cluster is ready to serve traffic. This would make etcd health-check fully Kubernetes API complient. Signed-off-by: Siyuan Zhang <sizhang@google.com>

Should we backport e2e tests too? |
|
In order to backport the e2e test, it would require backporting a lot of the e2e test framework, because existing Failpoint is in a this agent handler which is very hard to reuse. Is that worth the effort? @serathius |
|
Yes, it requires some effort, but we should not add features without proper e2e test coverage. Please let me know if you need help with backport. |

Note, I didn't mean that we should backport the e2e framework changes, just backport the e2e test. |

Looking at the e2e framework backports I think it would be easier to move it to separate PR so we ensure it's properly reviewed. |
