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.

Replaced multi-line strings with \n and concatenation #3462

If multi-line strings are used, the encoding of the source file will determine the result. Since the same file generates *nix and Windows scripts, no encoding will be correct except if explicit \n markers are used.
