> Dynamic node resource configuration: core scheduler changes

> As the first step, we go for resource change on RM side and expose admin APIs
> (admin protocol, CLI, REST and JMX API) later. In this jira, we will only
> contain changes in scheduler.
> The flow to update node's resource and awareness in resource scheduling is:
> 1. Resource update is through admin API to RM and take effect on RMNodeImpl.
> 2. When next NM heartbeat for updating status comes, the RMNode's resource
> change will be aware and the delta resource is added to schedulerNode's
> availableResource before actual scheduling happens.
> 3. Scheduler do resource allocation according to new availableResource in
> SchedulerNode.
> For more design details, please refer proposal and discussions in parent
> JIRA: YARN-291.
