* 4) After start container call is successful nmtoken should have been
* saved in NMTokenSecretManagerInNM.
* 5) If start container call was successful (no matter if container is
* still running or not), appAttempt->NMToken should be present in
* NMTokenSecretManagerInNM's cache. Any future getContainerStatus call
* for containerId belonging to that application attempt using

* nmToken error. (This can be best tested if we roll over NMToken
