 NMTokenCache is a singleton. Because of this, if running multiple AMs in a 
 single JVM NMTokens for the same node from different AMs step on each other 
 and starting containers fail due to mismatch tokens.
 The error observed in the client side is something like:
 {code}
 ERROR org.apache.hadoop.security.UserGroupInformation: 
 PriviledgedActionException as:llama (auth:PROXY) via llama (auth:SIMPLE) 
 cause:org.apache.hadoop.yarn.exceptions.YarnException: Unauthorized request 
 to start container. 
 NMToken for application attempt : appattempt_1382038445650_0002_01 was 
 used for starting container with container token issued for application 
 attempt : appattempt_1382038445650_0001_01
 {code}

Attachment: YARN-1321.patch

Updated patch following an offline chat with Vinod, Bikas and Sandy.

* The {{NMTokenCache}} class has detailed javadocs on how to be used with high 
level client APIs and low level protocol APIs
* The {{ContainerManagementProtocolProxy}} has a new constructor that takes a 
{{NMTokenCache}} instance (instead of a setter)
* Removed unnecessary cache setter methods
