Attention Needed

This patch release enables the etcd corruption checks on every etcd member that is running etcd 3.5 (which applies to all Kubernetes 1.22+ clusters). This change is a recommendation from the etcd maintainers due to issues in etcd 3.5 that can cause data consistency issues. The changes in this patch release will prevent corrupted etcd members from joining or staying in the etcd ring.
