Wangda Tan updated YARN-1449:
-----------------------------
    Description: 
As described in YARN-1197, we need add API/implementation changes,
1) Add a "changeContainersResources" method in ContainerManagementProtocol
2) Can get succeed/failed increased/decreased containers in response of 
"changeContainersResources"
3) Add a "new decreased containers" field in NodeStatus which can help NM 
notify RM such changes
