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.
