Support ZConfig on no-ZServer environments

The current way to configure queues is to use ZConfig, but unfortunately it depends on ZServer being around, and unless you are @datakurre you might not be using ZServer on python 3 🙂

I spend way too much time to admit here trying to get that to work, and I thought I could finally find the light at the end the tunnel seeing how `haufe.requestmonitoring` is being configured, but alas, it is by no means a 1:1 thing, again too much time spent with this as well 🤷🏾

Why is so complicated to define some options in ZConfig? 🤦🏾
