    Normalize the scheduler weights.
    
    If somebody wants to implement any weighter different than RAM we
    have to ensure that all weights are normalized before doing anything
    with them (that is, before applying the multiplier and before we sum
    the calculated weight to the object). In this change all the weights
    are normalized to 1, so that the final weight for a host will be:
    
        weight = w1_multiplier * norm_w1 + w2_multiplier * norm_w2 + ...
