ServerGroupSoftAffinityWeigher implements the soft-affinity policy for server groups as it orders the hosts by the number of instances running on them from the same group in decreasing order. ServerGroupSoftAntiAffinityWeigher implements the soft-anti-affinity policy for server groups as it orders the hosts by the number of instances running on them from the same group in increasing order. Both weigher assumes the the RequestSpec object refers to a valid InstanceGroup object which has a populated members field. This will be provided by the subsequent patch. New configuration options added: * soft_affinity_weight_multiplier * soft_anti_affinity_multiplier Add docs about the new weigher classes and change the function name 'weigh_object' to '_weigh_object' in the Weights section to match the code.
