      1. Proposed title of this feature request

      Allow disabling force detach of volumes from non-responding nodes in Openshift cluster.

      2. What is the nature and description of the request?

      In Openshift currently when a node is non-responsive (or more precisely when kubelet is non-responsive or not running), after a pod is deleted the volume can be force detached from the node even though it may be mounted on the node.

      Currently this feature can be disabled in KCM by specifying flag disable-force-detach-on-timeout, but Openshift provides no way to configure this - https://kubernetes.io/docs/concepts/cluster-administration/node-shutdown/#storage-force-detach-on-timeout

      3. Why does the customer need this? (List the business requirements here)

      In certain cluster types, force detaching a volume in this way can cause volume's data or file system to become corrupt. This not a safe operation and hence cluster-admin should have option to disable it.

      4. List any affected packages or components.
