[Users] Adding Iscsi storage to Ovirt All-in-one config

[Rick Beldin]

I set up an ovirt 3.1 all-in-one config with Fedora and added one node.
Created virtual machines and so forth.  All seems to work well.

I then decided to add iscsi and can verify that both the ovirt node and
the all-in-one node can 'see' the storage even though it is uninitialized
and does not have a partition table:

# parted /dev/mapper/1IET_00010001 p
Error: /dev/mapper/1IET_00010001: unrecognised disk label
Model: Linux device-mapper (multipath) (dm)
Disk /dev/mapper/1IET_00010001: 52.4GB
Sector size (logical/physical): 512B/512B
Partition Table: unknown
Disk Flags:
