Creating a base interface

As we mentioned previously, an interface is a contract, plain and simple. The interface for our base microservice is going to be relatively simple. The following is what our interface looks like:

public interface IBaseMicroService
{
void Start(HostControl hc);
void Stop();
void Pause();
void Continue();
void Shutdown();
void Resume();
void TryRequest(Action action, int maxFailures, int startTimeoutMS = 100, int resetTimeout = 10000, Action<Exception> OnError = null);
Task TryRequestAsync([NotNull] Func<Task> action, int maxFailures, int startTimeoutMS = 100, int resetTimeout = 10000, [CanBeNull] Action<Exception> OnError = null);void PublishMessage(object message, string connStr = "host=localhost", string topic = "");
Task PublishMessageAsync(object message, string connStr = "host=localhost", string topic = "");
}

You will notice that our interface, aside from the TryRequest functions, really only controls the motion of our microservice. This means...
