Remove Netty dependency exclude from tests

[cppwfs]

To disable the activation of the Netty server when using the inprocess server add @AutoConfigureTestGrpcTransport to the test.

Thanks.
I don’t know what this annotation is doing and I don’t say that there is something wrong in your solution, but I wonder if there is some overlap with this annotation and those explicit properties for `inprocess'. In general I have feeling that if I go this annotation, then I don’t need those properties: they should be inferred from this annotation . Perhaps some further idea how to improve Spring Boot experience

This was based on a recommendation from @philwebb. In short AutoConfigureTestGrpcTransport
enables auto-configuration of the GrpcServletRegistration, GrpcServerFactory, GrpcChannelFactory. When using this annotation the defaults for these autoconfigurations is false, thus in our case the servlet engine is not autoconfigured.

You are correct that we can now remove the explicit properties.
