Thanks [~bteke], I'm not sure if I'll have time to work on this anymore, so you 
can take it over if you want.

> 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 Certain statements in the documentation are no longer valid, for example: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.
