[Libvirt-cim] [PATCH 0 of 2] Virt_ComputerSystemIndication

This one stops leaking some of the memory from the ind_args struct and adds a little more verbosity to some error messages per Dan's request. I didn't add system name to the "Failed to create ind" one, because it was not readily available already and the extra code to get it didn't seem worth it, but I put in all the information that is available at that point.
