[PATCH] virsh: Add source-initiator opt to build the initiator of pool XML
For iscsi-direct pool, the initiator is necessary for pool defining:
<pool type="iscsi-direct">
...
<initiator>
<iqn name="iqn.2013-06.com.example:iscsi-initiator"/>
</initiator>
...
</pool>
Add --source-initiator to fill the initiator iqn for
pool-create-as/pool-define-as subcommands.
