Turn of retry-limit for AkkaProtocolStressTest #3466

 This test drops messages, but dropping too much will make it fail. The reason is that this test expects at least a few of the final messages to arrive to prove that the Remoting does not get stuck in an irrecoverable state. The retry limit enabled case is covered by the SystemMessageDelivery tests. This is basically a revert to the original configuration.
