Enable test_iscsi_volume in live migration job
The block_migrate_cinder_iscsi config option in Tempest says
the libvirt driver doesn't support live migration with an attached
volume because of bug 1398999 where volumes live on a network share
like RBD. However, I8fcc3ef3cb5d9fd3a95067929c496fdb5976fd41 in
nova says that this is possible with libvirt >= 1.2.17. Since we are
using libvirt 2.5.0 from the Ubuntu Cloud Archive on Xenial nodes
now, we should be able to enable this test.

Bug description:
When an instance with attached Cinder volumes is block migrated, the
Cinder volumes are block migrated along with it. If they exist on
shared storage, then they end up being copied, over the network, from
themselves to themselves. At a minimum, this is horribly slow and de-
sparses a sparse volume; at worst, this could cause massive data
corruption.
