Description

The new added load qos controller should only get USAGE SLACK resources but not ALLOCATION SLACK resources.

for (const ResourceUsage::Executor& executor : usage.executors()) {
        // Set kill correction for all revocable executors.
        if (!Resources(executor.allocated()).revocable().empty()) {
          QoSCorrection correction;

          correction.set_type(mesos::slave::QoSCorrection_Type_KILL);
          correction.mutable_kill()->mutable_framework_id()->CopyFrom(
            executor.executor_info().framework_id());
          correction.mutable_kill()->mutable_executor_id()->CopyFrom(
            executor.executor_info().executor_id());

          corrections.push_back(correction);
        }
      }
