aiohttp 0.18 release

[asvetlov]

We have a long change-list for next release.

My the last showstopper was signal support.
I've get finally satisfactory solution with #562

What do we want to have on the plate until ship will sail?

Maybe #542 and #543 but I'd like release shortly and publish a release with async for support in next few weeks.

Opinions?

+1 for release

+1. I couldn't make multipart async for support for 0.18 release, but will till the next.
