6 minute force-deatch timeout should be used only for nodes that are not
healthy.
In case a CSI driver is being upgraded or it's simply slow, NodeUnstage
can take more than 6 minutes. In that case, Pod is already deleted from the
API server and thus A/D controller will force-detach a mounted volume,
possibly corrupting the volume and breaking CSI - a CSI driver expects
NodeUnstage to succeed before Kubernetes can call ControllerUnpublish.
