Implement async/await interface

[tshemsedinov]

Implement async/await interface in addition to events and callbacks.

• Constructor const logger = await new Logger();
• Open await logger.open();
• Close await logger.close();
• Rotate await logger.rotate();

Can you, please, give a hint on implementation of async/await in constructor?

I've found it in your "Async programming" course.
But I still can't understand - does "in addition" mean that we will be able to call constructor and other methods both inside async functions and in synchronous code?
E.g.?:

(async () => {
    const logger2 = await new Logger();
})();

const logger3 = new Logger();

See this for example: https://github.com/metarhia/config/blob/master/config.js#L11
You can call it const config = await new Config(path);

If we return promise from constructor we definitely need to wrap await new into async function
