New test case: gen versus swap via gateway

A new test was added: tests/basicrapid_gw.test. Traffic generated will
now go to the reflector (swap instance) via the Gateway. The swap
instance will also send the traffic back via the gateway. This use case
is created to support GCP testing where the interfaces are defined with
a /32 netmask, and hence all traffic is routed via the gateway.
