> Make DN minimum valid volumes configurable

>
> The minimum number of non-faulty volumes to keep the DN active is hard-coded
> to 1. It would be useful to allow users to configure this value so the DN
> can be taken offline when eg half of its disks fail, otherwise it doesn't get
> reported until it's down to it's final disk and suffering degraded
> performance.
