Description

When calling RpcService.connect the user specifies the type of the RpcGateway. At the moment, it is not checked whether the RpcEndpoint actually supports the specified RpcGateway.

I think it would be good to add a runtime check that the corresponding RpcEndpoint supports the specified RpcGateway. If not, then we can let the connect method fail fast.
