Code Issues Proposed changes

Makes the iSCSI initiator name unique for compute nodes 

When we utilise images for deployment, the iSCSI initiator name
is not unique, leading to problems with live migration. This
patch simply updates the iSCSI initiator name to a unique ID
randomly generated by iscsi-iname.
