-------------------------------------

We might be able to leverage the existing {{getPendingReason}} RPC to expose this information.

> --preemption_delay (see https://github.com/apache/incubator-aurora/blob/master/src/main/java/org/apache/aurora/scheduler/async/preemptor/PreemptorModule.java#L47-L50) isn't documented in the user-guide https://github.com/apache/incubator-aurora/blob/master/docs/user-guide.md#user-content-giving-priority-to-production-tasks-preempting and since it is a system setting the end user has noway of knowing an an operator might have set it to.
> Right now when a production job is submitted and the cluster is "full" of non-prod jobs the prod job will go into "PENDING" state and the user will see a message such as "Insufficient CPU"  There is no acknowledgement that the job will attempt to preempt non-prod jobs after some operator configured amount of time.  This is confusing to users.
> I propose when a prod job cannot be immediately scheduled the UI gives the user a message that says something to the effect "Will attempt to preempt non-production Jobs in ~9m42s"
