feat(scope-manager): implements AsyncHooks Scope Manager

[vmarchaud]

I'm waiting on #100 to be merged so i can add more tests (and coverage) and itirate on this PR.

Specific mention: i believe we are forced to cast to any in the bindFunction, if someone have an idea feel free to tell !

@vmarchaud something like this might work

[vmarchaud]

@bterlson Thanks for looking into it, sadly it doesn't wort either because your signature missed the fact that bindFunction return T, see this one

Ready to be merged following discussion from SIG

A few small nits, but then should be good to go 👍

LGTM. Could use more tests that the scope is actually propagated properly with all the different asynchronous constructs, but these can be added later.
