Disable Netty eventloop graceful termination 

When shutting down the Netty event loop, we have already guaranteed that
all users of it are no longer running. Doing a shutdownGracefully is
just delaying graceful JVM termination by two seconds. This is very
noticeable for short-lived processes, like our integration tests.

We would actually also prefer to shutdown quickly and get a
RejectedExecutionException for any newly queued tasks, because that
would be a legitimate bug.

shutdown() is deprecated, thus we do shutdownGracefully with a timeout
of 0.
