Description

AbstractAutoCreatedLeafQueue extends the LeafQueue class which is an instantiable class, so every time an AutoCreatedLeafQueue is created a normal LeafQueue is configured as well. This setup results in some strange behaviour like having to pass the template configs of an auto created queue to a leaf queue. To make the whole structure more flexible an AbstractLeafQueue should be created which stores the common methods.
