Reduce the load excerted by the activator overload test. (#3532)

It should be enough for this test to use 100 concurrent connections. With a ContainerConcurrency of 1 that should still overload the service by a ton if throttling is not working properly. At the same time this reduces the stress this test puts on othe (unintended) layers in networking.
