> As mentioned by YARN-5906, currently schedulers are using ResourceRequest heavily so
it will be very hard to adopt the new PowerfulResourceRequest (YARN-4902).
> This JIRA is the 2nd step of refactoring, which remove usage of ResourceRequest from
AppSchedulingInfo / SchedulerApplicationAttempt. Instead of returning ResourceRequest, it
returns a lightweight and API-independent object - {{PendingAsk}}.
> The only remained ResourceRequest API of AppSchedulingInfo will be used by web service
to get list of ResourceRequests.
> So after this patch, usage of ResourceRequest will be isolated inside AppSchedulingInfo,
so it will be more flexible to update internal data structure and upgrade old ResourceRequest
API to new.
