VMware: should not take the first host found in the cluster to perform iSCSI related operations

[Arnaud Legendre]

When attaching an iSCSI volume, Nova triggers a HBA scan in order to
find the static targets and indirectly populate the SCSI topology in
vCenter.
The current implementation takes the first host found as the host to
perform the scan. This doesn't take into account the fact that the VM
can run on another host. This is problematic because then the host
where the VM is running is not aware of the target that the VM is
supposed to be attached to.
