---------------------------------------

Hi [~bteke],
Thanks for working on this. 
The PR looks good to me, committed to trunk.
As a matter of fact, we agreed on some minor fixes with [~bteke] so I made some changes locally and pushed the commit so that's why I closed the PR.
Thanks.

> The weight mode and AQC also affects how the new placement engine in CS works and the documentation has to reflect that.
> Certain statements in the documentation are no longer valid, for example:
> * create flag: "Only applies to managed queue parents" - there is no ManagedParentQueue in weight mode.
> * "The nested rules primaryGroupUser and secondaryGroupUser expects the parent queues to exist, ie. they cannot be created automatically". This only applies to the legacy absolute/percentage mode.
> Find all statements that mentions possible limitations and fix them if necessary.
