YARN-5605. Preempt containers (all on one node) to meet the requirement of starved applications.
- Remove existing preemption code.
- Deleted preemption tests, to be reinstated later.
- Identify starved applications in the update thread when preemption is enabled.
- For each starved application, identify containers to be preempted on a single node to make room for this request.
- Preempt these containers after necessary warning.
