Streaming support

[alexsv]

Hi,
I'm impressed by the framework, but want to check one thing:
I want to read big file and send a portions of it like 1KB by 1 second

So I expect, that HTTPResponse would accept some iterator.
Any ideas about this?

You could implement a custom protocol based on the base sanic HTTPProtocol.

Closed with #209

Am I right custom protocol is used for the whole application and I can't make one endpoint streaming based?

[seemethere]

@alexsv that would be correct. But I would think that there could be a better implementation out there that would not require changing the entire protocol just to enable it for one endpoint.

[alexsv]

possible on blueprint level?

[seemethere]

Possibly but it would need to be investigated.
