bug 8643: listCapacityCmd - Make the capacity calculation more optimal. Now the API wont recalculate the stats everytime its called. It would rely on the capacity checker thread running (configurable) every 5 mins to get the capacity. Change the initital delay of capacity check thread from 5 mins to 30 seconds so that we check capacity immediately as we log in.
