Implement nested snat validation test scenario
It's disabled for ovn because it's not, yet, implemented for the driver.
See: https://review.opendev.org/c/openstack/neutron/+/926495
(The feature also requires special configuration for the driver that we
probably won't enable in the gate. This can be discussed though.)
