Introduce new test case: symmetric service chain

JIRA: SFC-53

The goal is to verify that the traffic traverses the service chain, not only
in the uplink (client --> server) direction, but also in the downlink
(client <-- server) direction, which is the part that is not currently being
covered by other test cases.
