dev: Grpc.Net.Client throws System.Net.Http.HttpIOException

```
Unhandled exception. System.Net.Http.HttpIOException: The response ended prematurely while waiting for the next frame from the server. (ResponseEnded)

```

Should Grpc.Net.Client throw non-RPC errors?

Start with the stack trace through Grpc.Net.Client.Internal.StreamExtensions.WriteMessageAsync and HttpContentClientStreamWriter.WriteAsyncCore, then examine how System.Net.Http.HttpIOException is surfaced during HTTP/2 streaming. Done means the project has a decided, tested answer for whether this non-RPC error should be exposed or translated.
