Support Meteor 3

[leonardoventurini]

Remove fibers from the agent and integrate with Async Hooks and Async Local Storage.

[leonardoventurini]

Milestone

Tests pass on Meteor's future release 3.0 branch

[leonardoventurini]

Right now there is no way to know if a promise has been awaited or resolved in the background. What we can do is assume that an event which does not have other events in parallel has been awaited.

[zodern]

Would there be any async hooks/ALS metrics that would be useful instead? Can we track how many hooks or ASL stores are being used in the app?

[leonardoventurini]

I think we can, will research.

Thanks @StorytellerCZ. I'll look into it this week.

[brianlukoff]

@zodern I'm seeing the same error as @StorytellerCZ when trying to use the 3.0 beta -- it seems to be a conflict with matb33:collection-hooks starting with version 2.0.0-rc.0 of that package -- if I revert matb33:collection-hooks back to 2.0.0-beta.2 then there is no problem.

[StorytellerCZ]

Collection hooks recently got a fix from MS core team on one thing, so it might be a good idea to test again.

[brianlukoff]

@StorytellerCZ I had tried with 2.0.0-rc.3 -- is that the latest? (I was just trying to figure out which version of collection-hooks introduced the incompatibility and it looks like it was rc.0.)
