Thanks for the PR. Overall LGTM. I've suggested a minor naming change to keep consistent with other naming changes.

@georgekuruvillak Will you please merge this PR. And release the hotfix. This is urgently needed fix for alicloud deployment.

Change in the bootstrap ConfigMap leads the checksum annotation checksum/etcd-bootstrap-configmap to be updated which leads the etcd Pod to be restarted. For future cases I would appreciate if we mention similar details in the release notes (for example this PR will lead to etcd Pod restart (in the maintenance time window)).

[swapnilgm]

@ialidzhikov Sure. We will try to maintain those details in release notes.
