Rapidly cancelling a Call can overwhelm transport

See original GitHub issue

Doing something like

      ClientCall<Void, Void> call = channel.newCall(foo, CallOptions.DEFAULT);
      call.start(listen, new Metadata());
      call.sendMessage(null);
      call.halfClose();
      call.request(1);
      call.cancel();

rapidly in a loop causes memory to not get reclaimed. Somehow netty is holding on to commands sent to it from the ClientCallImpl.

I will. I am going to try and make the DefaultHttp2FrameWriter buffer these tiny writes up before sending so that so many tiny buffers aren’t created.
