Daniel Willmann 8d9fcf4461 gbproxy: Test routing if an SGSN in a pool is down If an SGSN in a pool is down we expect the messages to instead be sent to a different SGSN in the pool. That SGSN will not necessarily know what to do with those messages, but it should )implicitly) detach that UE so that it can reattach at the new SGSN. Otherwise UEs on a failed SGSN would simply stop working as the messages would never be forwarded anywhere. This test also adjusts the NS timers so the failed NSVCs are detected faster.
