> YARN-2882 and YARN-5430 broke compatibility by adding abstract methods to ContainerStatus.
Since ContainerStatus is a Public-Stable class, adding abstract methods to this class breaks
any extensions. 
> To fix this, we should add default implementations to these new methods and not leave
them as abstract.
