A weigher should be a subclass of ``weights.BaseHostWeigher`` and they must
implement the ``weight_multiplier`` and ``weight_objects`` methods. If the
``weight_objects`` method is overridden it just return a list of weights, and not
modify the weight of the object directly, since final weights are normalized and
computed by ``weight.BaseWeightHandler``.
A weigher should be a subclass of ``weights.BaseHostWeigher`` and they can implement
both the ``weight_multiplier`` and ``_weight_object`` methods or just implement the
``weight_objects`` method. ``weight_objects`` method is overridden only if you need
access to all objects in order to calculate weights, and it just return a list of weights,
and not modify the weight of the object directly, since final weights are normalized
and computed by ``weight.BaseWeightHandler``.
The Filter Scheduler weighs hosts based on the config option
`scheduler_weight_classes`, this defaults to
