[libvirt] [PATCH 2/4] doc/schema: Support iqn for storage pools

[Philipp Hahn]

iSCSO qualified names (iqn) from RFC3721 may contain colons (':'), which
neither matches the absFilePath nor genericName:

 $ virsh pool-dumpxml myiscsipool
 <pool type='iscsi'>
 ...
   <source>
 ...
     <device path='iqn.2003-01.org.linux-iscsi.phahn-sid93.x8664:sn.8a3daa0d4efd'/>
   </source>
 ...
 </pool>

Add IscsiQualifiedName type and allow its use in sourceiscsi.
