Example {@link ClientInterceptor} that logs all called methods in INFO log level, also request and response messages,
headers, trailers and interaction status in DEBUG log level. In this example it is added to Spring's application
context via {@link GlobalInterceptorConfiguration}, but is also possible to directly annotate this class with
{@link GrpcGlobalClientInterceptor}.
