Support ZConfig on no-ZServer environments

[gforcada]

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? 🤦🏾

I recall that queues are just registered components. So, if you have a queue that works on WSGI server, you should be able to skip the ZConfig part and register them with ZCML in a policy product 🤔

Btw, last week I was very happy to have ZServer with "good old products directory" also on Python 3 Plones...
