poc: server

[Uzlopak]

This is a poc for octokit/webhooks.js#932

I think I will also take some parts of this PR to the beta. E.g. loglevel is not passed through every layer, resulting in logging everything, which can slow down significantly.

I used npm link on the @octokit/webhooks.js branch I proposed to test it here. So the ci wont work.

Anyway here some naive benchmarks.

Because logging is not passed through the original performance is about 30 k/ 10 secs.
