CLOUDSTACK-4442: Include a test for creating networks with sourcenat only
The test attempts to create a network with offering serving only dhcp,dns and sourcenat. However the source NAT functionality itself isn't tested as reported in the bug. So the test will pass. TODO: come up with a way to test source nat without enabling additional services for pf/staticnat Signed-off-by: Prasanna Santhanam <tsp@apache.org>
