Add support for logical storage pools
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).
