🏃 Others

• [OPERATOR] Backup-restore waits for its etcd to be ready before attempting to update peerUrl (gardener/etcd-druid#602, @abdasgupta)
• [OPERATOR] When scaling from single-node to multi-node etcd cluster, Etcd Druid will now first ensure that any change to the peer URL (e.g TLS enablement) is seen by the existing etcd process running within the etcd member pod. Once that is confirmed then it will scale up the Etcd StatefulSet and add relevant annotations. (gardener/etcd-druid#602, @abdasgupta)
