------------------------------------------------------------

Uploading updated patch. Thanks [~jianhe].. 

* Added a new testcase for restart
* Added an authorization check to ensure only applications that started the container can
reinit/restart/rollback etc.
* Added some metrics to monitor the number of reinitialized and auto-rolledback containers.

Will fix the checkstyles (and add the Audit logs) once we are fine with the API / class names
etc.

> YARN-5620 and YARN-5637 allows an AM to explicitly *upgrade* a container with a new launch
context and subsequently *rollback* / *commit* the change on the Container. This can also
be used to simply *restart* the Container as well. 
> This JIRA proposes to extend the ContainerManagementProtocol with the following API:
> * *upgradeContainer*
> * *rollbackLastUpgrade*
> * *commitLastUpgrade*
> * *restartContainer*
