Introduce a new structure to handle an iSCSI host device based on the
existing virDomainHostdevSubsysSCSI by adding a "protocol='iscsi'" to
the <source/> element. The existing scsi_host subsystem RNG was modified
to read an optional "protocol='adapter'", although it won't be written
out nor is it documented as an option (by choice).
The new hostdev structure mimics the existing <disk/> element for an
iSCSI device (network) device. New XML is:
<hostdev mode='subsystem' type='scsi' managed='yes'>
<source protocol='iscsi' name='iqn.1992-01.com.example'>
<host name='example.org' port='3260'/>
<auth username='myname'>
<secret type='iscsi' usage='mycluster_myname'/>
</auth>
</source>
<address type='drive' controller='0' bus='0' target='2' unit='5'/>
</hostdev>
The controller element will mimic the existing scsi_host code insomuch
as when 'lsi' and 'virtio-scsi' are used.
