If the remote disk has already a partition table, it must be clean up
before the disk is exposed through iscsi. Otherwise this disk
partition can create a conflict during the grub installation.
start_iscsi_target() has now a new paramter wipe_disk_metadata to
request the agent to wipe the disk before exposing it.
Now, disk without preserve_ephemeral are cleaned up before new
deployment.
