It should be noted that filtering and veto stats also include preemption proposal evaluations.

> The number of invocations of the {{SchedulingFilterImpl.filter()}} method exposes the
number of offers examined per unit of time. And the number of vetos exposed by {{TaskVars}}
gives the number of offers vetoed for each veto group. But, none of these provide us with
visibility into how many offers are examined before a task is assigned in {{TaskAssignerImpl.maybeAssign()}}.
