> When AM calls NM via {{ContainerManagementProtocol}}, the NMToken is suppied for authentication.
The RPC server will verify the password of NMToken (originally generated by RM) so that we
know the content of NMTokenIdentifier is geniune. 
> Next, for {{stopContainers()}} and {{getContainerStatus()}}, method {{authorizeGetAndStopContainerRequest()}}
is used to verify that the requsted containers do belong to the AM by comparing them against
the AppId in NMTokenIdentifier. However, right now when the appId doesn't match, {{authorizeGetAndStopContainerRequest()}}
only log a warning message and continues to kill the container... Overall a malicious AM can
kill containers of other apps running in any node its containers are running.
