> Currently, ProportionalCapacityPreemptionPolicy has hard coded logic to select candidates
to be preempted (based on FIFO order of applications/containers). It's not a simple to add
new candidate-selection logics, such as preemption for large container, intra-queeu fairness/policy,
etc.
> In this JIRA, I propose to do following changes:
> 1) Cleanup code bases, consolidate current logic into 3 stages:
> - Compute ideal sharing of queues
> - Select to-be-preempt candidates
> - Send preemption/kill events to scheduler
> 2) Add a new interface: {{PreemptionCandidatesSelectionPolicy}} for above "select to-be-preempt
candidates" part. Move existing how to select candidates logics to {{FifoPreemptionCandidatesSelectionPolicy}}.

> 3) Allow multiple PreemptionCandidatesSelectionPolicies work together in a chain. Preceding
PreemptionCandidatesSelectionPolicy has higher priority to select candidates, and later PreemptionCandidatesSelectionPolicy
can make decisions according to already selected candidates and pre-computed queue ideal shares
of resources.
