Change DevicePath attribute to DevicePaths
This is because logical storage pools can take more than one device path

Add support for logical storage pools
Note: These changes don't add support for creating the volume group (in the
case where one doesn't already exist). That functionality will be added in
a later patch. This means you will need an existing volume group already
defined in order to test.
For now, you can create a volume pool just by specifying the following
attributes:
-Type and Path (in the DiskPoolRASD)
-ElementName (param of the CreateChildResourcePool() method).
