Very weird. I have re-implement graceful termination to do the exactly what forceful termination does, but use SIGTERM instead of SIGKILL, still the results are different. In 3 node cluster terminated cluster is unable to bootstrap raft, it hangs somewhere between connecting to other members and publishing member to cluster. Issue doesn't happen in single node cluster.

Is there something wrong with e2e testing framework or etcd? cc @ahrtr

Added a draft commit to on top for easier reproduction of the issue.

I think it might be some issue with peer proxy in e2e framework. https://github.com/etcd-io/etcd/actions/runs/8425584127/job/23072006524?pr=16788
