SAP is reporting issues with the v2 cgroup setting and requesting we go back to v1. Given that we have no othet known consumers of the CHOST images we honor this request. That said the change to v1 may cause issues with k8s (https://kubernetes.io/docs/concepts/architecture/cgroups/).
Depending on the protocol version for SSH we need to set either ChallengeResponseAuthentication or KbdInteractiveAuthentication to "no". Prior to this change we only set ChallengeResponseAuthentication allowing password based login when the SSHv2 protocol is used. We now modify newer config files appropriately.
