e2e use functional options to configure NetworkingTest
NetworkingTest is used to test different network scenarios. Since new capabilites and scenarios are added, like SCTP or HostNetwork for pods, we need a way to configure it with minimum disruption and code changes. Go idiomatic way to achieve this is using functional options.
