Latency sensitive edge functions

[steve-chavez]

Problem

A user reported that the webhooks had a latency of 1 second in various cases. This can be true as we read from the net tables when a 1 second timeout is reached, if a webhook is triggered at the end of the read, the webhook will be fired after 1 second passes.

We cannot read from the tables all the time since this would result in too much activity.

Solution

Start doing requests immediately whenever the net.http_* functions are called. Now that we use epoll, perhaps we can do it with eventfd.

This should also be easier to do with an in-memory queue.
