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.

This change is meant to allow running operators locally on a developer machine.
The idea is to allow faster development cycles by reducing the time and complexity of building -> deploying -> debugging on cluster.
For operators that rely only on kubernetes API this works easily - see cockroachdb and minio examples in development-flow doc.
The change includes:
- rook.NewContext() - Refactored to remove repeating initialization code that was copy-pasted in most of the operators in order to create the clusterd.Context and the Clientsets. Also it detects the mode of working in-cluster vs external and sets up the external mode with standard user config (~/.kube/config) and a job executor.
- rook.GetOperatorImage() - Refactor this repeating code in many operators to detect the operator pod image. Also added a global flag --operator-image that developers can use to override this when running locally.
- rook.TerminateOnError() - Added a convenient function.
Fixes the issue that when the old IPv4 flags were set, the new flags
were still used because of the default being the new flags not being
empty.
Added `NetworkInfo()` func to cmd/ceph to get simplified network info

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.
