[virt-tools-list] [PATCH] virt-manager:Add "vSCSI disk" and "vSCSI cdrom" option into Device type in "add hardware" page



From: Qing Lin <qinglbj linux vnet ibm com>

1.Add "vSCSI disk" and "vSCSI cdrom" option into device type on
"add storage page".
2.Add sPAPR-vSCSI controller when it's needed.
When vSCSI controller doesn't exist,there are two situations to 
add it:one is when adding a vSCSI disk, another is when 
an existing disk is changed into sPAPR-vSCSI bus type.
3.Fix Disk Lable text  on details page.
