Hello,

I would like to be able to test my app's interactions with the dapr sidecar in an integration test. However, io.dapr.testcontainers.DaprContainer is currently hard-coded to use HTTP as the app protocol. How much effort would it take to add a DaprContainer.withAppProtocol() method so we can test with gRPC?

If it seems like something a newbie like me could handle, let me know.

Thanks!
