nova: Ensure each compute uses a unique iSCSI initiator

Browse Source 
The current initiator name embedded in our CI images is not unique at
present and can often cause failures during live migrations with
attached volumes. This change ensures the name is unique by running
iscsi-iname again and overwriting the existing name.

We could potentially do this during the image build process itself but
given that devstack systems are not supposed to be multi-purpose this
should be safe to do during the devstack run.
