run "rook discover" on storage nodes and discover devices on each node. The discovered disks are saved in a per node configmap, local-device-nodename. Device information consits of name and persistent names, uuid, partition, filesystem, rotational, readonly, size, etc. Signed-off-by: Huamin Chen <hchen@redhat.com>
