verbose console output

Proposal

It would be great to see gRPC requests in the console just like http requests with the '-v' flag

I can do this in tests, e.g. I can change the config in GrpcAcceptanceTest, adding a notifier:

@RegisterExtension
public static WireMockExtension wm =
    WireMockExtension.newInstance()
        .options(
            wireMockConfig()
                .dynamicPort()
                .withRootDirectory("src/test/resources/wiremock")
                .extensions(new GrpcExtensionFactory())
                .notifier(new ConsoleNotifier(true)))
        .build();

Strangely, I also needed to create a new Wiremock object in the init method, similarly to the test in wiremock-grpc-demos

void init() {
//  wireMock = wm.getRuntimeInfo().getWireMock();
  wireMock = new WireMock(wm.getPort());

I'm using the standalone in a dockerfile, though, and I'd like to set up request logging there. I can't figure out how to do that. My dockerfile is quite simple. I set some options in the entrypoint, but there's no way I can see to add a notifier.

FROM wiremock/wiremock:3.5.4

COPY services /home/wiremock/grpc
COPY mappings /home/wiremock/mappings
COPY extensions /var/wiremock/extensions

ENTRYPOINT ["/docker-entrypoint.sh",  "--global-response-templating", "--disable-gzip", "--verbose"]

I've been hacking around with the source code, and I've got something that works for me. I don't know whether it's the best way to do it, though.

In the GrpcHttpServerFactory. we can pass the configured notifier into the GrpcFilter:
final GrpcFilter grpcFilter = new GrpcFilter(stubRequestHandler, fileDescriptors, options.notifier());

The GrpcFilter stores that as a new field, and then passes it on to the handlers that it builds. (I've only tested this with the UnaryServerCallHandler.)
new UnaryServerCallHandler(stubRequestHandler, serviceDescriptor, methodDescriptor, jsonMessageConverter, notifier));

The handlers also store the notifier as a new field, and then set the it in the LocalNotifier thread-local before invoking stubRequestHandler.handle:

LocalNotifier.set(notifier);
stubRequestHandler.handle(...

I 'll create a pull request if I find time next week.
