-----------------------------------------
Fixing this as a part of YARN-713 where I am restructuring the token generation
logic.
> RM may issue expired container tokens to AM while issuing new containers.

> Today we create new container token when we create container in RM as a part
> of schedule cycle. However that container may get reserved or assigned. If
> the container gets reserved and remains like that (in reserved state) for
> more than container token expiry interval then RM will end up issuing
> container with expired token.
