[Libvirt-cim] [PATCH 3 of 3] Add support for representing a cdrom device using the DiskDrive class

[Kaitlin Rupert]

This set of changes breaks the behavior of several providers.  Those 
issues need to be addressed and included in this patchset before it can 
be applied.

Broken behavior:
   ElementAllocatedFromPool:
	-Can no longer associate a disk to the pool it was allocated from.
	-Can no longer associate a pool to the disks that have been allocated 
from it

  SettingsDefineCapabilities:  Can no longer generate template RASDs for 
disk and cdrom devices

  DiskResourceAllocationSettingData:  enum doesn't return instances for 
DiskDrives

  ResourceAllocationFromPool: Unable to associate DiskRASDs to pools or 
pools to DiskRASDs

Need to check to see if conn is NULL.
