----------------------------------
Committed to trunk, thanks [~asuresh], there're some dependencies to backport
to branch-2, including YARN-6040, will backport the dependencies first.
> Unify Container Resizing code paths with Container Updates making it

> YARN-5959 introduced an {{ContainerUpdateContext}} which can be used to
> update the ExecutionType of a container in a scheduler agnostic manner. As
> mentioned in that JIRA, extending that to encompass Container resizing is
> trivial.
> This JIRA proposes to remove all the CapacityScheduler specific code paths.
> (CapacityScheduler, CSQueue, FicaSchedulerApp etc.) and modify the code to
> use the framework introduced in YARN-5959 without any loss of functionality.
