MockWebServer: streaming response (SSE)

[artem-zinnatullin]

I might be wrong, but looks like MockWebServer does not allow "endless" responses controlled by writing to body Buffer.

I'm trying to simulate Server Sent Events with setting Buffer as a body of MockResponse and keep connection open via not closing the Buffer. But whatever I do MockWebServer closes connection for me and does not allow me emulate SSE.

Basically, I'd like to keep connection until I explicitly close() body Buffer and be able to write data to socket via writing to body Buffer.

What about adding such API to MockResponse? i.e. MockResponse.setStreamingBody(Buffer body).

Buffer is not safe for use across threads and it's unclear what MWS would be doing during this. Just spinning in a hot loop or waiting for a notification? We don't have a good type to model this and it would probably need something more sophisticated like RequestBody which can block on the writer thread or web sockets which have their own API.

Tracking as #2916

Right, Buffer requires some wrapper to make it thread safe + add push/pull based API. I'll track #2916 then, thanks.
