Both are possible ways of doing it. This is more consistent with how node
locality is handled i.e. PTOperator contains list of operators that should be
co-allocated. Advantage of having the anti-affinity list of containers in each
container is it makes it easy to assign host to container requests based on
anti-affinity list.
