STELLAR-3554 : add support for stream resume, frame bundling

[davidk81]

• support for frame bundling
• support for stream resume
• grpc flow control with client telemetry message ack

I was testing the current release of the CLI and found go-grpc threw an error when the message size was over 4MB or so. I think there's a limit on the client too?

do we need to make resumeStreamMessageAckId into a cli argument so users can manually resume a stream if CLI fails to reconnect automatically?

i think this is ready for review

Do we print the ack ID anywhere? I don't think we need to have an argument for this since the CLI is handling this automatically. I couldn't imagine a user somehow recording the ack ID from CLI output and having a process restart the CLI with the recorded ack ID-- at this point it would be easier to just use the API directly 😄

not sure if this solves that problem, but this might be the way to set maxMessageSize in grpc-go. i didn't bother to figure out how to send messages > 4MB with starpass so i didn't test this.
