async_hooks: initial async_hooks implementation

Fill this commit messsage with more details about the change once all
changes are rebased.

* Add lib/async_hooks.js

* Add JS methods to AsyncWrap for handling the async id stack

* Introduce AsyncReset() so that JS functions can reset the id and again
  trigger the init hooks, allow AsyncWrap::Reset() to be called from JS
  via asyncReset().

* Add env variable to test additional things in test/common.js
