Issue MESOS-1620: Reconciliation does not send back tasks pending validation / authorization.
Per Vinod's feedback on https://reviews.apache.org/r/23542/, we do not send back TASK_STAGING for those tasks that are pending in the Master (validation / authorization still in progress). For both implicit and explicit task reconciliation, the master could reply with TASK_STAGING for these tasks, as this provides additional information to the framework.
