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>

Schema changes and pool_parsing changes needed to add SCSI pool support
For SCSI pools (pools using a host bus adapter) will need to specify the
AdapterName attribute. The PortName and NodeName attributes are optional.

Update xmlgen to generate SCSI storage pool XML, add support to RPCS
This adds the code necessary to read in the SCSI pool related attributes and
then generate the appropriate XML.

Expose SCSI template DiskPoolRASD in SettingsDefineCapabilities
Since PortName and NodeName are optional, this will need to be reworked some
so that both template types are exposed. That will be in a follow-up patch,
since it involves restructuring the function.
