v0.23.1

[gardener/etcd-druid]

⚠️ Breaking Changes

• [OPERATOR] If you wish to downgrade from druid v0.23.x to versions =<v0.22.7, please ensure that you change the CLI flags for the druid command to remove the new CLI flags introduced in v0.23.0. If you are using the provided helm charts to deploy druid, you may ignore this and simply deploy the helm chart, which takes care of the CLI flag changes for you. by @shreyas-s-rao [#894]

📰 Noteworthy

• [OPERATOR] etcd-backup-restore has been bumped to v0.30.2 and etcd-wrapper has been bumped to v0.2.0. by @shreyas-s-rao [#894]

🏃 Others

• [USER] Fixed the ready condition for the Etcd resource. by @shreyas-s-rao [#894]
• [OPERATOR] Fixes for handling of pod template labels, label-selector, replicas and TLS changes to Etcd resource. StatefulSet does not allow update of label-selector. v0.23.x changes the label-selector, to get that reflected in the STS, it will be orphan deleted and subsequently created. Similarly for peer TLS and pod label changes an update of pods will be done. For single member etcd clusters this will cause a transient downtime. If replicas, TLS, label-selector are changed together then it will also cause transient quorum loss in multi-node etcd clusters. by @shreyas-s-rao [#894]
