>   /**
>    * Encapsulate an offer from a host, and the host's maintenance mode.
>    */
>   class HostOffer {
>     private final Offer offer;
>     // TODO(wfarner): Replace this with HostAttributes for more use of this caching.
>     private final MaintenanceMode mode;
> {noformat}
> Success here will mean avoiding O(n) (n=num offers) fetching of host attributes associated
with offers when scheduling a task.
