Description

We have made some cosmetic changes to SchedulerNode recently. While working on YARN-4511, realized we could improve it a little more:

1. Remove volatile variables - don't see the need for them being volatile
2. Some methods end up doing very similar things, so consolidating them
3. Renaming totalResource to capacity. YARN-4511 plans to add inflatedCapacity to include the un-utilized resources, and having two totals can be a little confusing.
