PopulateDeviceInfo() in pkg/clusterd/disk.go returns nil as *sys.LocalDisk
if an error has occurred. This causes a nil pointer exception at
getAvailableDevices() in pkg/daemon/ceph/osd/daemon.go. At least the returned
value should be checked at the caller.
I added an explicit error to the return value of PopulateDeviceInfo(). This
naturally revokes an error check at the caller.
I modified PopulateDeviceUdevInfo() in the same file too.

- Added code to support StorageClassDeviceSet spec provided in the cluster-on-pvc.yaml
- The code reads the StorageClassDeviceSet spec and creates pvc based on the ‘count’ field for each device set.
- OSD prepare job is started for each PVC which activates the ceph-volume on each PVC
- Finally OSD is started on each of the PVC device.

Linear raid can be created using `mdadm --create --level=linear`,
By creating a linear raid disk on top of a logical volume,
we can pass the linear device to `ceph-volume lvm batch --prepare`
to provision a new OSD on top of the logical volume since
`ceph-volume` does not take lv as the data device.

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.
