             Summary: Display requested and assigned cpu/mem resources for schedulers in UI
                 Key: STORM-1144
                 URL: https://issues.apache.org/jira/browse/STORM-1144
             Project: Apache Storm
          Issue Type: Improvement
          Components: storm-core
            Reporter: Zhuo Liu
            Assignee: Zhuo Liu


For CPU/Mem resource-aware schedulers, it is important for us to provide the feedback information about how much resources (onheap memory, offheap memory and CPU) have been requested by user and assigned by scheduler for each topology, on the UI pages.

Tasks:
1. Calculate the requested and assigned onheap memory, offheap memory and CPU in resource-aware scheduler.
 2. Add data structures and REST api to support these resources in topo-info, topo-summary, topo-page-info, cluster, core, nimbus.
 3. Display assigned cpu/mem at the index page, and show more details about the requested and assigned resources at each topology page.
 4. Adjust the items shown on UI (delete topoId item, exclude topoId from schedulerInfo). Update the restful API doc.
