[libvirt] [PATCH v5 1/5] qemu: Add source pool auth info to virDomainDiskDef for iSCSI

[John Ferlan]

During qemuTranslateDiskSourcePool() execution, if the srcpool has been
defined with authentication information, then for iSCSI pools copy the
authentication and host information to virDomainDiskDef.
