Add more iSCSI examples including having a secret attached. There are 4 new
examples one for each way to have an iSCSI - a network disk using virtio,
a passthrough network lun using scsi, a volume disk using "mode='host'",
and a volume disk using "mode='direct'"

specifies the name of storage pool (managed by libvirt) where the disk
source resides, and attribute <code>volume</code> specifies the name of
storage volume (managed by libvirt) used as the disk source. For a
- "volume" type disk, if the underlying storage pool is "iscsi", attribute
- <code>mode</code> (<span class="since">since 1.1.1</span>) can be used
- to indicate how to represent the LUN as the disk source. The value
- "host" indicates to use the LUN's path as it shows up on host, e.g.
- /dev/disk/by-path/ip-10.11.12.9:3260-iscsi-iqn.2013-06.fc:iscsi.iscsi0-lun-1).
- The value "direct" indicates to use the storage pool's
- <code>source</code> element <code>host</code> attribute as the
- disk source for the libiscsi URI, e.g.
+ "volume" <code>type</code> disk, if the underlying storage pool is
+ "iscsi", then use the output of the value from the "Name" column of
+ the <code>virsh vol-list [pool-name]</code> command for the
+ <code>volume</code> attribute field. Use the attribute
+ <code>mode</code> (<span class="since">since 1.1.1</span>) to
+ indicate how to represent the LUN as the disk source.
+ Using "direct" as the <code>mode</code> value indicates to use the
+ storage pool's <code>source</code> element <code>host</code>
+ attribute as the disk source to generate the libiscsi URI, e.g.
file=iscsi://demo.org:6000/iqn.1992-01.com.example/1.
+ Using "host" as the <code>mode</code> value indicates to use the

+ /dev/disk/by-path/ip-10.11.12.9:3260-iscsi-iqn.2013-06.fc:iscsi.iscsi0-lun-1).
+ If <code>mode</code> is not specified, the default is to use "host".
