Currently the weight value is hardcoded for anti-affinity type preferredDuringSchedulingIgnoredDuringExecution. This ps updates the htk function to retrieve the weight value from the configured setting if it exists, or default to use the original hardcoded value of 10 if it is not set (for backward compatibility).
