grpcbox is is inconsistent with chatterbox/h2_client

[carolcarolus]

Hi,

I noticed that grpcbox uses functions that do not exist. For example, grpcbox_subchannel.erl(line 96) uses:
case h2_client:start_link(Transport, Host, Port, options(Transport, SSLOptions), #{stream_callback_mod => grpcbox_client_stream}) of
There is no five argument function in chatterbox application.

Unfortunately it is required to create a new stream.

I am using the latest versions of grpcbox and chatterbox.

@carolcarolus I have a fork of chatterbox that grpcbox is using. I have not merged it into chatterbox because, even though I maintain chatterbox now, I have not had anyone to help with reviews. I hope that changes now and we will see updates to chatterbox soon and remove the need for my fork.
