      Description

      As discussed in YARN-3784, there are scenarios like few other applications released containers or same application has revoked its resource requests. In these cases, we may not have to preempt a container which would have been marked for preemption earlier.
      Introduce a new event to remove such containers if present in the to-be-preempted list of scheduler or inform AM about such a scenario.
