Description

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Certain statements in the documentation are no longer valid, for example: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