[Libvirt-cim] [PATCH 0 of 3] Add support for SCSI (host bus adapter) type pools

[Kaitlin Rupert]

This set of changes is for scsi pools that are based on a host bus adapter.  These types of sotrage include FiberChannel attached storage devices, as well as
SANs.  There's two different ways to define these pools:

FiberChannel connected devices:
<pool type="scsi">
 <name>hba0</name>
  <source>
    <adapter name="host4"/>
  </source>
  <target>
    <path>/dev/disk/by-id</path>
  </target>
</pool>


SAN devices:
<pool type="scsi">
 <name>npiv</name>
 <source>
  <adapter name="host6" wwpn="0000111122223333" wwnn="4444555566667777"/>
 </source>
 <target>
  <path>/dev/disk/by-id</path>
 </target>
</pool>
