> When cancelling a pending slot allocation request on the {{ResourceManager}},
> then we should also check whether we still need all the requested containers.
> If it turns out that we no longer need them, then we should try to cancel the
> unnecessary container requests. That way Flink will be, for example, a better
> Yarn citizen which quickly releases resources and resource requests if no
> longer needed.
