igw: Update tests to use ceph-iscsi package

gateway_ip_list is depreciated and is only used when using the old
ceph-iscsi-config/cli packages that are no longer being developed
(GH repos are archived). Because ceph-iscsi-config/cli is no longer
being worked on, this modifies the tests to stress the ceph-iscsi
based installs.
