preferredDuringSchedulingIgnoredDuringExecution:
description: The scheduler will prefer to schedule pods
to nodes that satisfy the affinity expressions specified
by this field, but it may choose a node that violates
one or more of the expressions. The node that is most
preferred is the one with the greatest sum of weights,
i.e. for each node that meets all of the scheduling
requirements (resource request, requiredDuringScheduling
affinity expressions, etc.), compute a sum by iterating
through the elements of this field and adding "weight"
to the sum if the node matches the corresponding matchExpressions;
the node(s) with the highest sum are the most preferred.

all objects with implicit weight 0 (i.e. it's a
