> 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*
