Summary: [ceo] [release-4.6] Operator goes degraded when a second internal node ip is added after install

Fixed In Version: Doc Type: Bug Fix
Doc Text:
Cause: A second internal ip address is added to one or more control plane nodes. Consequence: The Etcd Operator goes degraded due to detecting the ip address change as a potential etcd membership change and does not regenerate etcd serving certificates for the node. Fix: The Etcd Operator differentiates between an ip address change for an existing node and for a new node. The operator will regenerate serving certificates for changes to an existing node. Result: Adding an ip address to a control plane node no longer results in the operator going degraded.
