Issue MESOS-2127: killTask() should perform reconciliation for unknown tasks.
Currently, {{killTask}} uses its own reconciliation logic, which has diverged from the {{reconcileTasks}} logic. Specifically, when the task is unknown and a non-strict registry is in use, {{killTask}} will not send TASK_LOST whereas {{reconcileTask}} will. We should make these consistent.
