[issue32193] Convert asyncio to async/await

[Andrew Svetlov]

New submission from Andrew Svetlov <andrew.svetlov at gmail.com>:

As discussed several times before we need to convert `@coroutine` / `yield from` to async/await.

All existing functionality should keep working (like yielding from new style coroutine and `with (yield from lock)`.

We could deprecate the later though.

The change should be huge but there is no alternative, keeping `yield from` in stdlib looks uglier and uglier every year.

Unittests should be changed as well (keeping several `yield from` for checking backward compatibility is Ok).


Opinions?
