Subject: [PATCH] udev rules: introduce rules for cluster-md to confirm device

For cluster scenario, add device is different with native raid.
When a node issues adds a device, then the node will broadcast
a message with UUID to other nodes in the cluster. If receiving
node can find the device with the specific UUID, it must confirm
the device, otherwise reports it is missing.
