Right now we have to introduce some delay in clients so that a grpc port is assigned to daprd before the client tries to make a connection. The logic to handle this issue needs to be handled in the sdk instead.

Logs for this issue when delay is not introduced in client:

$ dapr run --app-id=rustapp --grpc-port 3500 cargo run -- --example client
ℹ️  Starting Dapr with id rustapp. HTTP Port: 38035. gRPC Port: 3500

== APP == Error: TransportError
