> Expose stats on the number of offers evaluated before a task is assigned by
> {{TaskAssigner}}.
> 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 {{TaskSchedulerImpl.maybeAssign()}}.
