> In CS UserGroupMappingPlacementRule and AppNameMappingPlacementRule classes
> we create new instances of QueueMappingEntity class. In some cases we simply
> copy the already received class, so we just duplicate it, which is
> unnecessary since the class is immutable.
> This is just a minor improvement, probably doesn't have much impact, but
> still puts some unnecessary load on GC.
